Animal Garden - Hippopotamus

Hippos spawn in the savanna biome and can be tamed. Tamed hippos can be bred with wheat, grass, apples, melon slices and other vegetables, and only a pair of opposite genders produces offspring, which must be bred in or near water. Males are found less often than females, and larger hippos are less common still. Spawn weights, minimum and maximum group sizes, and other spawn settings can be changed in the config or through JSON data and biome tag files in a resource pack.

The mod requires Aquarius Libs. During the day hippos head to water to cool down, and at night they search for food and eat grass the way sheep do. Resting in water restores a little health. A tamed hippo can be set to wandering, which roams around a block the player marks, resting, which keeps it in place, or following, which makes it trail its owner, and Aquarius Libs shows a message when the behavior changes. Even tamed hippos sometimes attack, and feeding calms them down. Someone nearby may be attacked during a rampage, and a config option stops random attacks, while raising the random attack chance makes them less frequent.

Installation needs Aquarius Libs on Fabric, Forge or NeoForge. Both sides of a server need the mod, and every player joining it installs it too.
