Hungry Waters
by CorsicanFrog
Hungry Waters adds piranhas, a hostile water mob that starts hunting once its hunger bar empties.
What it does
Piranhas are a custom entity added by the mod. They spawn only in river, swamp and other water biomes, so players meet them while crossing or fishing in those waters. Each piranha carries a hunger bar, and when that bar reaches zero the fish switches into a hunting mode and goes after nearby living creatures, including players and other animals.
Piranhas also fight back when they are attacked, so striking one near a shoreline can bring others to the same spot. The mod is aimed at survival worlds and adventure maps where water crossings should carry some risk. Installation covers the server and each player's game. Files are published for Fabric and NeoForge, with 1.2.1 as the latest release for 1.21.5. Builds cover 1.21.1 – 1.21.11 across four release versions.
Key features
Custom piranha entity
Piranhas are added as a new mob with their own behavior, not as a reskin of an existing fish.
Hunger-driven hunting
When the hunger bar reaches zero, a piranha enters hunting mode and attacks anything alive nearby.
Retaliation
A piranha that is attacked fights back, so attacking one can draw a group into the fight.
Water biome spawning
Piranhas generate only in river, swamp and similar water biomes, keeping them out of open land.

Use cases
Survival water crossings
Players who build across rivers or swamps have to plan around hunting fish instead of crossing freely.
Who it’s for: Survival players and adventure map builders who want hostile water life. Server owners can add the mod to make waterways more dangerous, since every player on the server needs it installed.
