Minochi is a muscular Yo-kai that has a shape of a popped mochi, like Mochismo. Unlike him, Minochi is not stark white, but appears to be pink hued. He wears a black robe around his waist and has an aggressive look on his popped face.
When he puffs up his cheeks and exhales a ghastly steam the person he sprays becomes jealous and cannot help but act irrationally as a result. This power can affect entire crowds of Yo-kai as well as humans.
The fact he is a rice cake means he can be eaten in an emergency, but that also allows him to be eaten to submission.
"Yakimochi" is derived from yakimochi (焼き餅, "roasted mochi"). It is also an idiom for "jealousy". It is unsure how this idiom came to be, but one theory traces it back to a homophony between yaku (妬く, "to be jealous") and yaku (焼く, "to burn, to roast").
"Minochi" is a combination of mine and mochi.
Minochi's "random" nicknames in Yo-kai Watch 2 are: NV, Brad, Tuff, and Pinky.
