Sneech is the fox-faced rich kid who loves to flaunt his material wealth before everyone. He's also a member of the Weekenders Adventures team. Some of the stories start with Sneech showing off some new video game or toy which evokes Noby's envy. He is often seen with Big G. He sometimes despises Noby and often makes fun of Noby, most often resulted in Noby getting in trouble. He also often pushes Noby aside with excuses while he invites Big G. and Sue to his parties or resorts. In the films, Sneech is often the one most reluctant to take part in Noby and Doraemon's adventures, and he also tries to face as little trouble as possible and go home unless others convince him, making him somewhat a coward. He has an extensive knowledge of science, and is a talented artist and designer.

In some scenes, Sneech is seen as a narcissist who loves to stare at himself in the mirror while telling himself that he is the most handsome guy in the world. He is still a bed-wetter, despite being in the fourth/fifth grade. He considers this humiliating habit his secret weakness. Sneech is also very self-conscious about his height, being the shortest kid in his class. He likes steak and melon.
