The Boat Jacker is a huge, slender, purple muscular fish who wears a ski mask, a torn up dark blue jean jacket, and dark blue pants. He carries a crowbar.
This fish steals the Patty Wagon and later goes into a bar. SpongeBob and Patrick have to develop a plan to get the key back, which is successful.
"Out of the car fellas."
"It's...uh...right over there."
The Jacker was in The SpongeBob SquarePants Movie video game, only smaller, and in the levels "Thug Tug" and "Dennis Strikes Back." The Jacker in the game, however, has a different voice and grunts which are higher pitched than in the movie.
