The Yoda character does not work with Mimic because the head was replaced, and its creator, WarriorDL, did not include the morph targets that Mimic uses to move the mouth and blink the eyes. The morphs appear in the dial lists, but they're left over from the original P4 Male figure, and won't work with the new head. To make it work, you must remove and replace the morphs. I have some experience with this, and could create a working version overnight, but I'd need WarriorDL's permission to post the new .cr2.
