Seymour Scales is the antagonist of the Wii game SpongeBob's Boating Bash. He claims he is a professional boating teacher who can teach SpongeBob to drive with his "patented learning system, D.R.I.V.E." After giving SpongeBob a phony license, he tries to drive away but is defeated by SpongeBob and becomes an available driver for Quick Play mode.
Seymour Scales is light bluish-gray and wears an ivory-colored shirt, purple pants, and a red and tan striped tie. He also has orange hair and eyebrows.
He tricks SpongeBob into a D.R.I.V.E. learning course for boating so SpongeBob can get his license, but teaches him the wrong way to drive. He is an unlockable playable character in the game, and the main antagonist in the game.
When Seymour said, "And I would've gotten away with it too, if it wasn't for Mrs. Puff's meddling around!" he is referencing the television series Scooby-Doo.
Alongside all the other sharks in Bikini Bottom, Seymour is the only one with orange hair.
