Goop
Goop lets slimes and magma cubes leave splatter when they hit the ground and when they take damage, with optional blood on living entities.
What it does
Goop is a client-side visual mod that adds slime splatter effects in the game. Slimes and magma cubes leave puddles behind and create ground splatter when they take damage. Blood is handled through damage emitters that are added to living entities where it makes sense, and some mobs bleed in different colors. Only the red blood is marked as mature content, and the other effects can be censored through the client config.
Goop is an open source mod released under the MIT License, first published on 2023-09-25 and last updated on 2025-05-04. It needs Cloth Config API and Fabric API, and runs on Fabric or Quilt for 1.20 – 1.21.5 across eight release versions. The client needs it, while the server can skip it. Snapshot builds are not covered here.
Key features
Slime splatter effects
Slimes and magma cubes leave puddles behind and splatter on the ground when they hit it, which is a purely visual change.
Damage-driven blood
Damage emitters are attached to living entities where it makes sense, so hits produce blood that fits the mob.
Mob-specific colors
Some mobs bleed in colors other than red, so the splatter varies by creature.
Mature content controls
Only the red blood is marked mature, and an option can turn all blood effects off by default or leave them on.

Use cases
Gory adventure maps
Map makers who want splatter effects on hostile mobs can use the damage emitters to add visual feedback to fights.
Censored servers
Players who prefer a milder look can use the client config to censor the other effects while keeping slime splatter.
Who it’s for: Players who want slime and blood splatter effects on the client, and players who prefer a configurable amount of gore. Server owners need no install because the server is optional.
