Animal Pens Expansion – Alex's Caves
by BONNe
With Animal Pens Expansion – Alex's Caves installed, the animal pens from Animal Pens also hold creatures from Alex's Caves, such as the Sea Pig and Gummy Bear.
What it does
The addon connects two Forge mods. Animal Pens Expansion – Alex's Caves requires Alex's Caves and Animal Pens, and it enables Alex's Caves mobs inside Animal Pens. Players can pick these animals up with a water bucket or an acid bucket, and some can be picked up in a soda bucket, an Animal Cage or a Bird Catcher. Each mob is fed with a specific food, such as spelunkie, radgill, candy cane or sweet fish, and a Water Container can be picked up as well.
The server side adds the extra interactions, and the client side adds animations for mobs kept in Aviary and Aquarium blocks. Primordial frogs have a variant that drops a carmine froglight. The mod is released under the GNU General Public License v3.0 only and is open source, with its source code and issue tracker public. Files target Forge 1.20.1, and the latest release, 1.2.0, is dated 2026-06-17.
