Walkappa is a kappa Yo-Kai.
Soultimate-Mega Waterfall.
In the anime, Nate meets Walkappa after he and Whisper are arguing about if kappas are real or not. After that, Nate summons Walkappa, when he is trying to befriend Tattletale. That is the only time that Nate has used Walkappa. In the game, you befriend Walkappa, after you bring him 3 Karp, and then you can use him as many times as you want, and once you let it evolve into Appak, you can get another Walkappa in the rivers, or in the Catfish Pond.
Thanks so much for reading, and the next part will be about, Baku.
Like I have said in the other chapters, if you want to battle, just message me your friend code, and I will friend you, and then we can battle. (Hint: I will be using only S rank Yo-Kai, so make sure to be prepared).
Thanks so much, and keep on reading.
