Walkappa in Yo-kai Watch 1

Upon listening Bear's story of how he lost a ring in Catfish Pond, Nate/Katie goes looking for a kappa to help Bear out. Along the bank of the west canal, Nate meets Walkappa in the disguise of a sunflower, and weak from hunger. Walkappa agrees to help the protagonist out in exchange for three carp for lunch, though Nate has no fishing rod, then Walkappa remedies that problem by giving him one to catch the fish.

As promised, the protagonist brings Walkappa the three carp who wolfs them down and thanks them by giving them his Yo-kai Medal. Later the protagonist talks to Bear at Catfish Pond, who is still looking for his mom's ring, and summons Walkappa to help look for the ring, who makes a big show of splashing around the pond for the ring. Walkappa finds the ring, but all the splashing and water acrobatics drew the ire of Catfish Pond's boss, SV Snaggerjag, and attacks the protagonist. After the fight, Walkappa apologizes for his wild swimming, then gives the protagonist the Special Ring Bear was looking for.

During the events of Walkappa's Bottle, occurring sometime after the Lost Ring incident, Walkappa had lost his bottle and tasks the protagonist & Whisper in finding it along the west canal, though all they found was trash. They eventually find the bottle at Catfish Pond after grilling some more info from the kappa Yo-kai.

He can be found in the river in Uptown Springdale.
