Sketch Lampoon
From Sonic Retro
Sketch Lampoon is an artist and comic book creator for the fictional "Mad-like" magazine called "Crack Ups". He is some sort of goofy bird that wears a neck-tie.
In Sonic Breakout one of his comics, which featured Robotnik, gets him in trouble with Robotnik. He is taken hostage and forced to draw Robotnik to his liking. As a retaliation for his being taken hostage he swears to draw a sequel to the comic that Robotnik disliked the most and make Dr Robotnik look even worse.
He makes a reappearence in Hero of the Year as one of the guests at Sonic's party.
