He is a large, dark lime green squid. He wears a purple bandanna over his eyes and a white t-shirt. He also drives a large, blue boat with a bumper, that looks like one from a train, in the front, turbo engines in the back, and the number "6" in red text on the side. Blow Torch can breathe fire, hence his name.
Role in episode
He first appears when Captain Lutefisk introduces him at the beginning of the Demolition Derby. He shares a laugh with the Kruncher after seeing SpongeBob pull up. He attempts to crash into SpongeBob, but ends up getting his face run over by SpongeBob. He tries one last attempt to crash into SpongeBob, but fails and ends up colliding with a lifeguard's boat, losing the Derby.
Not counting SpongeBob and Mrs. Puff, he is one of two characters that competed at the Demolition Derby and had any speaking lines, the other being the Kruncher.
