Glow Squid

The glow squid is proof that Minecraft players will vote for literally anything if it glows. Winner of the 2020 Minecraft Live mob vote — beating out the Iceologer and Moobloom — the glow squid is an aquatic passive mob that drifts through dark underwater caves looking like it swallowed a blacklight. Despite what its name suggests, it does not actually emit light. Not a single light level. It just looks like it does. Welcome to Minecraft, where “glow” is a suggestion, not a specification.

You will find glow squids swimming aimlessly in underground water sources, usually below Y-level 30. They behave almost identically to regular squids — floating around, getting stuck in corners, and occasionally squirting ink when you smack them. The key difference is their ink is glow ink, which has some genuinely useful crafting applications. So while the mob itself is about as exciting as watching paint dry, what it drops is actually worth your time.

Think of the glow squid as a luminous vending machine. You do not hang out with it for the conversation. You show up, collect the goods, and leave. The glow ink sacs it drops are used for making glow item frames and glowing sign text, both of which are incredibly handy for builds and decoration. So even if the mob itself is a bit of a wallflower, its contribution to the game earns it a permanent spot in your underwater farming plans.

Overview / Quick Stats

Appearance

The glow squid uses the same model as the regular squid — a blocky body with eight short tentacles dangling beneath it. The difference is entirely cosmetic but immediately obvious. Where the regular squid is a dark navy blue, the glow squid sports a teal-cyan texture with bright, glowing markings across its body.

Those glowing markings pulse rhythmically, creating a slow hypnotic animation that cycles between bright teal and a dimmer state. It looks like the squid is breathing light. The effect is purely visual — it does not produce any actual block light or affect the light level of its surroundings at all. The glow is rendered as an emissive texture, meaning it appears bright even in total darkness, similar to how Enderman eyes or Spider eyes work.

When a glow squid takes damage, the glowing effect temporarily stops. The texture dims to a darker, muted version for a few seconds before the glow resumes. This is actually a useful visual cue — if you see a dark glow squid, something just hit it.

Behavior & AI

• Movement: Glow squids swim aimlessly in water, drifting in random directions with no particular goal. They use the same AI as regular squids — periodic bursts of movement followed by idle floating. They have no pathfinding to speak of and will frequently get stuck against walls, in corners, or wedged into one-block gaps.
• Passive Nature: Glow squids never attack and never flee from the player. They are completely indifferent to your existence. You can stand right next to one and it will continue its aimless drifting without a care in the world.
• Ink Squirting: When a glow squid takes damage, it squirts glow ink particles (teal-colored) in all directions and attempts to swim away. This is a purely cosmetic defense — the particles do not inflict any status effects or obscure vision like regular squid ink does in Bedrock Edition.
• Suffocation on Land: Like regular squids, glow squids cannot survive on land. If they end up outside of water, they flop around helplessly and take suffocation damage after 15 seconds (300 ticks), eventually dying. They have zero ability to return to water on their own.
• Despawning: Glow squids follow standard passive aquatic mob despawn rules. In Java Edition, they can despawn if no player is within 128 blocks. In Bedrock Edition, they follow similar distance-based despawn rules but may persist longer in loaded chunks.
• Darkness Preference: Glow squids only spawn at light level 0 in Java Edition, so you will almost exclusively find them in underground cave pools and deep ocean trenches. This is thematically perfect — the one place where their fake glow actually looks impressive.
• Water Dependency: Glow squids require a water source to survive. They cannot exist in lava and take fire damage normally. They also cannot swim in waterlogged blocks — they need actual water source or flowing water blocks.

Abilities, Attacks & Status Effects

• Attacks: None. Glow squids have no attack capability whatsoever. They are one of the most defenseless mobs in the game.
• Glow Ink Particles: When damaged, glow squids emit teal-colored ink particles. Unlike Bedrock Edition’s regular squid ink cloud (which can briefly obscure the player’s screen), glow ink particles are purely visual and have no gameplay effect.
• Hypnotic Glow (Minecraft Earth Callback): In the cancelled Minecraft Earth, glow squids had an ability to hypnotize the player. This was not carried over to the main game. Despite some early speculation, glow squids in Java and Bedrock Editions have no mesmerizing or status-inflicting abilities.
• Glow Effect on Damage: When hit, the glow squid’s emissive texture temporarily deactivates. The mob turns dark for about 5 seconds before the glow resumes. This is a visual-only mechanic with no gameplay impact.
• Immunities: None. Glow squids take damage from all standard sources — melee, projectiles, fire, lava, suffocation, and fall damage (if somehow launched out of water).

Spawning

Interactions with Environment & Other Mobs

• Axolotls: This is the big one. Axolotls actively hunt and kill glow squids on sight. If you have an underwater cave with both mobs spawning, the axolotls will systematically wipe out the glow squid population. This is important to know for farming — you either need to keep axolotls out of your glow squid farm or accept that your teal friends are going to have a very bad time.
• Guardians and Elder Guardians: Guardians will attack glow squids just like they attack regular squids. Do not expect glow squids to survive near Ocean Monuments.
• Other Hostile Mobs: Drowned and other underwater hostile mobs will not specifically target glow squids, but glow squids can still take incidental damage from tridents thrown at the player.
• Boats and Minecarts: Glow squids can be pushed by boats but cannot ride in them. They have no minecart interaction.
• Leads: Glow squids cannot be leashed with a lead.
• Water Currents: Glow squids are affected by water currents, which is essential knowledge for building farms. You can use water flow to funnel them into kill chambers.

Drops & Loot

Player Uses & Farming

• Glow Ink Sacs — Primary Use: Glow ink sacs are used to make sign text glow (apply to any sign to make the text luminous and readable in the dark) and to craft glow item frames. Both are incredibly useful for builds — glowing signs are visible without torches, and glow item frames make maps and decorative items pop in dark rooms.
• Crafting Glow Item Frames: Combine 1 glow ink sac with 1 item frame at a crafting table. The glow item frame lights up whatever is placed inside it without needing an external light source. Perfect for map walls in underground bases.
• Removing Glow from Signs: If you apply a regular ink sac to a glowing sign, it removes the glow effect. This works both ways — glow ink sac adds glow, regular ink sac removes it.
• Farm Design — Basic Concept: Glow squid farms exploit their spawning requirements. Build a dark water chamber below Y=30, with water currents that push spawned glow squids into a central kill point. Use magma blocks on the floor to pull squids down and deal damage, or funnel them into a drop chamber where they die from fall damage or campfire smoke.
• Farm Design — Key Principles: Light-proof the spawn chamber entirely (Java requires light level 0). Make sure no axolotls can access the farm — they will kill your glow squids and steal the drops. Use hoppers or hopper minecarts beneath the kill zone to collect glow ink sacs automatically.
• Expected Rates: A well-built glow squid farm can produce several hundred glow ink sacs per hour, depending on the platform and farm size. Bedrock farms tend to produce more because of the relaxed light level spawning requirement.
• Edition Caveats: Bedrock Edition farms are simpler to build because there is no light level requirement below Y=30 — just build the water chamber and you are good. Java farms require total darkness, which means no light leaks at all. One misplaced torch or uncovered opening can tank your spawn rates.

Commands & NBT

Here are some useful commands for working with glow squids:

/summon minecraft:glow_squid ~ ~ ~

Basic summon at your current location. Make sure you are standing in or near water, or the glow squid will immediately start suffocating on land.

/summon minecraft:glow_squid ~ ~ ~ {Silent:1b,Invulnerable:1b}

Summons a silent, invulnerable glow squid — useful for decorative builds or custom maps where you want the ambient glow without the mob dying to random environmental damage.

/summon minecraft:glow_squid ~ ~ ~ {NoAI:1b}

Summons a glow squid with no AI. It will float in place without moving, which is perfect for aquarium builds or display tanks.

• DarkTicksRemaining: Integer tag that tracks how long the glow squid’s glow effect is deactivated after taking damage. Measured in ticks. When set to 0, the squid glows normally.
• NoAI: Standard tag. Setting to 1b freezes the glow squid in place — it will still glow but will not move or squirt ink.
• Invulnerable: Setting to 1b prevents all damage. Combine with NoAI for permanent decorative glow squids.
• Silent: Setting to 1b suppresses all ambient and hurt sounds.

Tags, Gamerules & Datapack Hooks

• #minecraft:axolotl_hunt_targets: Glow squids are included in this entity tag, which is why axolotls target them. Removing glow squids from this tag via a datapack will stop axolotls from hunting them.
• #minecraft:aquatic: Glow squids belong to the aquatic entity tag, which affects mob cap calculations and despawning behavior.
• #minecraft:not_scary_for_pufferfish: Glow squids are in this tag, meaning pufferfish will not inflate when a glow squid swims near them.
• Loot Table Path: minecraft:entities/glow_squid — Modify this loot table in a datapack to change what glow squids drop. You could add custom drops or adjust glow ink sac quantities.
• Gamerule doMobSpawning: Setting to false prevents glow squids from spawning naturally. Existing ones remain.
• Gamerule doMobLoot: Setting to false prevents glow squids from dropping glow ink sacs and experience.

Difficulty & Edition Differences

• Difficulty Scaling: Difficulty level does not affect glow squids at all. They deal no damage and have fixed health across Easy, Normal, and Hard. The only indirect effect is that hostile mobs that might incidentally damage glow squids (like Drowned) become more aggressive on harder difficulties.
• Java vs. Bedrock — Spawning: Java Edition requires light level 0 for glow squid spawning below Y=30. Bedrock Edition has no light level restriction, only the Y-level requirement. This makes glow squids significantly more common and easier to farm in Bedrock.
• Java vs. Bedrock — Ink Particles: The glow ink particle effect when a glow squid is damaged looks slightly different between editions due to particle rendering differences, but the behavior is functionally identical.
• Java vs. Bedrock — Despawning: Java Edition glow squids follow standard aquatic mob despawn rules based on distance. Bedrock Edition has slightly different chunk-loading behavior that can affect how long glow squids persist in unloaded areas.
• Java vs. Bedrock — Axolotl Interaction: Axolotls hunt glow squids in both editions, but the combat animations and pathfinding to reach the squid can look slightly different due to entity AI differences.

Sounds & Audio

• Ambient: entity.glow_squid.ambient — Soft, underwater gurgling sound played periodically while the glow squid is alive. Nearly identical to regular squid ambient sounds.
• Hurt: entity.glow_squid.hurt — Short squelching sound when the glow squid takes damage.
• Death: entity.glow_squid.death — A wet, deflating sound when the glow squid dies.
• Squirt: entity.glow_squid.squirt — Played when the glow squid emits glow ink particles after being hit.

History & Major Changes

• Minecraft Live 2020: The glow squid was announced as one of three mob vote candidates alongside the Iceologer and Moobloom. It won the vote, partly fueled by social media campaigns and content creator endorsements.
• Java 21w03a (1.17 Snapshot): Glow squid added to Java Edition. Initially spawned in any dark water body regardless of Y-level.
• Java 1.17 (Caves & Cliffs Part I): Glow squid officially released. Dropped glow ink sacs, enabling glow item frames and glowing sign text.
• Bedrock 1.17.0: Glow squid added to Bedrock Edition with the same drops and behavior.
• Java 1.18 (Caves & Cliffs Part II): Spawning restrictions updated — glow squids now only spawn below Y=30 to match the expanded underground terrain. This concentrated them in deeper cave systems and made them less common in shallow water.
• Java 1.18.2: Minor spawning weight adjustments to balance underground mob populations after the terrain generation overhaul.

Notable Bugs & Quirks

• The “Fake Glow” Misconception: Despite being called a glow squid, this mob emits zero light. The glow is an emissive texture effect rendered on the mob model, not a light source. Placing a glow squid in a dark room will not illuminate anything. This has confused players since day one and will probably continue to confuse players forever.
• Land Beaching: Glow squids occasionally spawn at the edge of water pools and immediately beach themselves, where they flop around and die. This is not technically a bug — it is the same behavior regular squids have had for years — but it does feel like a mob that lives exclusively underground should be smarter about staying in water.
• Axolotl Genocide: In worlds with lots of underground water and natural axolotl spawns, glow squids can be nearly impossible to find alive because axolotls kill them so efficiently. Some players never see a living glow squid in survival without specifically seeking one out.
• Despawn Frustration: Since glow squids can despawn in Java Edition, players who travel away from underground areas and return may find their glow squid populations have vanished. Named glow squids (via name tags) will not despawn.

Advancements / Achievements

• “Glow and Behold!” (Bedrock Achievement): Awarded for using a glow ink sac on a sign to make the text glow. This is one of the easiest achievements in the game — find a glow squid, punch it, pick up the sac, and apply it to any sign.
• “The Cutest Predator” (Java Advancement): While not a glow squid-specific advancement, killing a glow squid with an axolotl can contribute to the advancement related to axolotl interactions. The glow squid is one of the mobs that counts as an axolotl hunt target.
• “Adventuring Time” (Java Advancement): Visiting the biome where glow squids spawn does not specifically count for this advancement, but exploring underground cave biomes (where they are commonly found) does.

Spin-offs, Culture & Trivia

• Mob Vote Controversy: The glow squid winning the 2020 mob vote was one of the most debated outcomes in Minecraft community history. Many players felt the Iceologer (a hostile mob that would have added new combat challenges) or the Moobloom (which interacted with bees) were more interesting additions. The glow squid’s victory is often attributed to content creator Dream publicly endorsing it to his massive audience.
• Minecraft Earth Origins: The glow squid first appeared in the now-discontinued Minecraft Earth AR game, where it had a hypnotic ability that could mesmerize the player. This ability was not brought to the main game, leaving the glow squid with even less functionality than some players expected.
• Running Joke: “It does not actually glow” became a community meme almost immediately after the mob’s addition. Players who voted for the glow squid expecting a new light source were vocally disappointed when they discovered it was purely cosmetic.
• Merchandise: The glow squid has appeared in official Minecraft merchandise, including plush toys and figurines. Its distinctive teal coloring makes it a popular design choice despite the in-game controversy.
• Aquarium Builds: Despite the community complaints, the glow squid has become a favorite for aquarium and underwater base decorations. Its glowing texture makes it look impressive in dark builds, and using name tags to prevent despawning lets players keep them as permanent aquatic decorations.
