The Rubber Pants Commandos are a team of gun-toting babies who occasionally come to Sam & Max' rescue (usually with impeccable timing). They appeared in Night of the Gilded Heron-Shark and later in Max's Big Day and The Final Episode. They are lead by the chimpanzee Sergeant Blip. According to Steve Purcell, they are named Pip (holding the knife) and Zip (bowl-cut).
