Marty Mennis was a member of Shaky's gang. He drove the getaway car after Shaky abducted Snowflake Falls from police headquarters. After Shaky and his accomplices reached their hideout, Marty discovered the word "Snowflake" that had been written in the dust on the car's exterior by Junior Tracy. He informed Shaky that the word was still visible even after the car had been washed (since the dust had scratched the word into the paint).
