Buggin' Out : Season 1 Episode 45

Vexor commands Combat Gnat to spy on Hillhurst when Flabber brings a teletransport machine from an old drawing to life. Flabber transports himself to Zoom Comics and shortly thereafter realizes he's morphing into a strange creature. When he remembers that there was a blue bug in the machine with him, he and the kids surmise that his molecular structure merged with Combat Gnat's! The kids decide that the only solution is to send this unpredictable being into the comics, which magically reverses the damage - Flabber is back!
