📋 About This Mod
This mod adds a fully customizable creature size randomizer.
Random Creature Sizes Mod
This mod is currently in beta, so expect occasional bugs or jank.
Random Creature Sizes Mod dynamically changes the size of fish, creatures, and leviathans throughout the world using a weighted bell-curve distribution. Creatures can spawn anywhere from 0. 2x to 30x their normal size, making both tiny variants and massive fish possible.
Extreme sizes are intentionally rare, meaning most creatures remain within believable ranges while occasionally generating giant leviathans or miniature fauna naturally.
