A food-based Yo-kai that is a red bowl of noodles and broth, with a pair of tentacle-like arms and human legs. He is wearing a simple purple mawashi like a sumo wrestler, and has a pair of pink narutomaki resembling cheeks. He also has a cinnamon stick and a egg sunny-side up on top of his head.
Sumodon can be found only when using a Traveller's Coin South, which has two different ways to obtain. One is with a Japanese-only Sumodon or Yokozudon Yo-kai Watch: Tomodachi Ukiukipedia card and with a series of 15 Passwords that can both be entered at Piggleston Bank for coins. The coins can be used to get Sumodon from the Crank-a-kai.
