A palette swap of Grubsnitch with beige skin, red irises, and black hair. He wears a green kimono, a darker beige straw skirt and a purple turtle shell on his back.
Wantston has a compulsive need to feel jealous of others. Despite expressing covetous desires, he refuses to put in effort to improve his situation so he can remain permanently envious. As a result, he feels disturbed when complimented since it removes his justification to feel envious.
Anyone Inspirited by Wantston becomes as envious as he is, and incessantly whines about desiring what others have, even negative traits or unwanted outcomes (such as feeling tired or getting into trouble). At the same time the Inspirited also refuses to change their situation and instead continue complaining. This often causes the Inspirited victim to be turned away by others for whining too much.
In the anime, Wantston seems to be capable of withstanding huge amounts of pain. Even attacking him cannot dispel the effects of his jealousy. His sole weakness is receiving compliments, which counteracts his influence.
Wantston appears in the Tucked Away Lot in Blossom Heights. The entrance is between Candy Stop and the Hot Springs.
Wantston Appears In The Delivery Bay In Downtown Springdale. He Also Appears In Gates of Whimsy.

Wantston appears in EP056 having already inspirited Nathan Adams. This makes him exhibit peculiar displays of jealousy over others feeling tired, getting into accidents and so on. Driven mad by this, Jibanyan uses Nate's Yo-Kai Watch to force Wantston out. Nate barely manages to summon Komasan and Komajiro (who hitched a ride with Komasan upon being summoned). Innocently, Komasan begins to compliment Wantston, making him unnerved much to the dismay of Komajiro. Catching on, Komasan and Komajiro compliment Wantston until he surrenders his Yo-Kai Medal and runs away.
