Chummer

Chummer appeared in 2013 video game called Yo-Kai Watch. Chummer (Japanese: ミチクサメ Michikusame) is a Rank C, Water-attribute Yo-kai from the Slippery tribe.

Chummer resembles an anthropomorphic shark with leafy greens in both his mouth and hand.

Chummer can make children loiter after school, then later he will devour them. In the anime, however, instead of eating children, he simply makes kids loiter so that magic weeds appear and he eats them. In the manga, he operates similarly to the manga, only instead of creating magic weeds, he makes the inspirited pull up weeds to eat them due to not being able to pull weeds up fast enough himself.
