He is an edited version of Myster Mouse made with You Doodle Plus for IOS. He is burning, has magma worms everywhere, and has 2 character’s heads on him. One is a edited version of Dark Dry Bowser, but FateForFranks can’t remember how he edited it, and the 2nd head is PN. Mickey. As for Sundying, the player had to put on the mickey mask to get rid of him.
He had artwork that can be seen when in the Misc menu.
FateforFranks is attempting to make a shade for him.
His jumpscare sound is Squidward from Five Night’s at Nicks.
