Similar to Chummer in appearance, Shrook is a turquoise-colored shark Yo-kai with cream-colored skin on his stomach His feet and hands are human-like, and they are darker than his stomach. He also has aqua blue sclera.
Shrook is somewhat of a bully, indicated by his taunting of those he Inspirits after turning them into amateurs, and seeks enjoyment from watching professionals embarrass themselves after he takes away their talent.
Anyone Inspirited by Shrook will lose any mastery of anything that they are good at and become novices once again. In the anime, Shrook does this by blasting the victim with a stream of fire from his mouth. Shrook is capable of returning the talents he steals if willing.

In the anime
Shrook appears in EP075 after he causes some street performers to mess up their acts. Once Nate identifies him, he refuses to cooperate and steals away Whisper and Jibanyan's talents so they can't use the Yo-kai Pad or the Paws of Fury. Nate challenges Shrook to take away his talent, demanding that Shrook return everyone's talents if he fails. Shrook agrees, but after Nate demonstrates his complete lack of talent due to being completely average, Shrook surrenders and gives up his Yo-kai Medal.
