Cosmic Skateboard

The Cosmic Skateboard is a pet item that drops from the Martian Saucer, with a 25% chance, in Master Mode. It summons an alien skater that will follow the player around.

Trivia

 * The phrase "How do you do, fellow humans?" is a reference to an infamous cutaway gag in the television show 30 Rock, in which Lenny Wosniak, (poorly) pretending to be a high school student, walks up to a group of teens and asks "How do you do, fellow kids?"
