Nightmare Fuel: You can take the punching bag wolfen out of the dojo (by grabbing its tail and pulling it outside). If you pull it all the way to the bottom of a nearby slide, then attempt to go up the slide, Kya will slide down, letting go of the fake wolfen. It will then stand in place like a real wolfen, and will rotate to watch Kya. (Any video showing this will be appreciated.)
The Scrappy: Akasa, the dojo owner, with his limited-but-incessant vocabulary, qualifies as this for many players.
