- Yo-kai Watch Wibble Wobble: Befriending Yo-kai
In his Lightside form, he looks like a traditional Kappa. He has green scaly skin, a plate on the head, and a turtle shell on the back. Unlike most Kappa Yo-kai, it appears that he has no beak. The cap on his head is blue. He also has a blue striped tie, along with a briefcase, which he holds due to the fact that he is a salaryman.
In his Godside form, Kappa is much taller and has a blue cap with red spiral hair around it and a blue outfit with grey scales on the top of his back. He also has armbands and seems to use a bow staff as a weapon
