what I want to do is be able to change the dragon into a biped and make it look like a human. whenever I try though, I just get a whole bunch of body parts separated out where the dragon counterparts should be. how could I go about doing that? Also, if it is possible, I could change for a new mob to spawn in the end instead of a dragon, but I don't know how to do that. Any help would be appreciated. Thank you.
