It looks like Kirby, but...what's with that face? This Kirby isn't the one everybody knows and loves. He hails from a fan comic whose author is a member of the Talking Time forums. In Super Squad, Kirby proves both adorable and completely ineffectual in his efforts to help "Unca Weegee" and the others to save the day. That's when he's not too oblivious to realize the day needs saving, which is basically never.
Kirby filled the role of helper character in Super Talking Time Bros. 2. In fact, the whole game was loosely based on the events of the Super Squad comic, so it wasn't at all out of place. Still, he falls somewhere between cute and creepy-clingy, so maybe don't give him the wrong idea about being friends.
