I caught these two butterflies, one is a yellow bird thing, and one is a purple demon thing. They're butterflies, though.

I can't get the yellow one to get off of the purple one's head, though. There's also a weird button on the purple butterfly's back, when I press the button, it falls asleep...but then the yellow butterfly moves and presses the button again, and it wakes up! Purple keeps trying to bite me, too...Does anybody know what kind of butterflies they are?
