"Puppy Pong", a rare alternate cabinet design for
Pong intended for use in non-coin-op environments such as waiting rooms or entrance-fee arcades, was originally designed after Snoopy from the
Peanuts comic strip. However, the concept was rejected by Charles Schulz, leading to the creation of a generic puppy in Snoopy's place. An unthemed version titled "Dr. Pong" was also released.
