Turn into any entity. It can be vanilla or modded. Just type "/morph [entity]" to transform into any creature, mob, or custom modded entity that you killed in your game. Fine for creative gameplay, and roleplay.
This mod allows you to morph into any entity in 1.20.1, including modded. This mod does not have the functionality(ghasts don't fly, zombies don't attack). You get the health, appearance, and animations of the entities you transform into.
