The Yo-kai Medallium bio reads: "If you can't stop snacking before dinner, Grubsnitch is probably nearby."
Grubsnitch resembles a small boy with tan skin, blue hair tied in a topknot, and round green eyes. He wears a beige kimono, a green straw skirt, and goes barefoot. He is usually seen drooling from the right side of his mouth.
In the game, Grubsnitch is a very gluttonous Yo-Kai, choosing to possess humans in order to pass on this trait and satisfy his hunger. When threatened, he does not budge and tries to fight back; however, he admits defeat when overpowered.
His favorite phrase, which is also present when possessing his targets, is "Otsumami!" ("It's just a bite!" in the English dub).
Abilities and Powers
Grubsnitch has the ability to possess humans and force them to snatch small pieces of bigger meals, and repeating until the whole meal is devoured. However, a strong enough desire to eat the whole meal -such as the one triggered by Hungramps's possession- can counter it rather easily.
Grubsnitch makes his debut in episode 23, causing Nate's Mother to snatch a small snack of the breakfast; however, he reveals himself when Nate's mother prepares a big dinner for her family. Said Yo-Kai possesses her and causes her to snatch small snacks from the meal. Nate tries to stop her mother to do so, but to no avail. Nate finally has the idea of summoning Hungramps to force his mother to eat the whole dinner in one step; soon, Hungramps and Grubsnitch start a possession battle with Nate's mother as the host, causing her wavering between snatching small snacks and devouring the meal in one step. Hungramps finally overpowers Grubsnitch, causing the latter to admit defeat and grant his Yo-kai Medal to Nate.
Its random names are: Sample, Dodd, Dinadash, and Drooly.
Grubsnitch might be based on the old urban legend of Perori Taro, about a boy with such an irrefrenable appetite for food his parents chased him out before he would drive them to starvation. From then on he wandered the country, getting hungrier and hungrier and begging people for food, causing them to run away when they saw him.
"Tsumamiguinosuke" is a combination of tsumamigui(つまみ食い, eating food before a meal begins) and suke (助), a common part of a male given name.
"Grubsnitch" is a portmanteau of the words grub, slang for generic food or to take food, and snitch, to steal or pilfer something of minimal value.
