Cross-Platform!
Mud Cake Monsters!
This mod gives you a special cake, that when consumed, will give you a five minute timer before the big poop. Depending on where you are when this timer expires, you could give "birth" to any one of three creatures. These creatures have the same stats of their vanilla counterparts, just a bit more flair.
Walking: Craptor
Swimming: Cnidiarrhea
Flying/Falling: Turdanodon
The mod is compatible with my Alpha Everything mod, and the newly birthed babies will have a chance to become an Alpha!
