Wotchagot appears to be a rice bowl with arms and a ghost-like tail. It has yellow sad-looking eyes and an open mouth, making it look aghast. Its bowl is a light-blue color, with a darker-blue dripping pattern around the top half of the bowl.
Anyone Inspirited by Wotchagot adopts its personality, feeling envious of other people's food under the assumption that it tastes better. The victim then proceeds to harangue others for a sample of their meal like a dispirited zombie.
Wotchagot is capable of regenerating its rice body after it is eaten, but repeated regeneration attempts in quick succession will eventually tire it out.
Wotchagot can be found in the Shopping Street Narrows (on Shoppers Row).
In the Anime
Wotchagot first appeared in EP070, where he Inspirited Nate'sparents, making them jealous of everyone's food. When Nate's parents and Wotchagot begin snitching food, Nate finds that Grubsnitch has also appeared. Grubsnitch encourages Wotchagot to snitch food it thinks tastes better, but then realizes that Wotchagot is made of rice and starts to eat Wotchagot. In response, Wotchagot demonstrates its regeneration ability, preventing Grubsnitch from winning. Seeing this, Nate summons Hungramps to help. Hungramps was able to eat Wotchagot entirely, leaving only Wotchagot's Yo-kai Medal behind, which Hungramps gave to Nate.
In EP074, he regenerated to help Pride Shrimp. As a result, Nate, Whisper and Jibanyan witnessed both Pride Shrimp and Wotchagot being eaten by Hungramps. They said that Hungramps is a scary Yo-kai.
Urayameshi's Japanese Soultimate Move name is a reference to Assault! Neighbor's Dinner (突撃!隣の晩ごはん, Totsugeki! Tonari no Bangohan), a reality TV show where the host barges into strangers' houses at evening to find out what they're having for dinner.
"Urayameshi" is a pun on urayamashii ("jealous, envious") and meshi ("rice serving", and by extension "food, meal").
"Wotchagot" is a corruption of the phrase whatcha' got?.
