Bruce

Bruce is the supporting character in The Wolf Who Saved The Little Girl He is a shark

He serves as a foil to Dave whom he tries to eat because he thinks he's a codfish, and literally sees him and the octopi as one.

In the movie, When Dave and his octopi return from Madison, they tie Taya Calder up in a bag on a net and throw some chum overboard to lure Bruce towards Taya so that, when Classified rescues her, he'll get eaten by Bruce too and Dave will have his revenge. When Classified arrives, Dave tells him that Taya is Belle and cuts the bag with his sword, sending Taya overboard and into the water with Bruce and Classified and Lola Sonnor both dive in after her. When both of them and the Octopus go under, and Dave believes that he has finally gotten his revenge on Classified, but then Classified and Lola come back up with Taya in the bag and Lola squirts pixie dust on Bruce, making the sea animal fall on the submarine, right on top of Dave. Upon tasting the octopus, Bruce mistakes Dave for a delicious fish and grabs Dave with his teeth dragging him back into the water, but the octopus is able to slip from the shark's grasp sending him flying back onto the submarine.

Later on, when Taya saves Classified from Dave, Dave grabs Taya, but Classified throws his sword at the rope to save Taya from Dave again. Dave fell through the submarine (because Classified threw an anchor on top of him), into the sea and straight on top of him. Bruce faces Dave and he once again mistakes him for a fish, and the terrified octopus frantically swims back to his ship, swimming through the hole in it with the shark in hot pursuit. The shark destroys a large portion of the the submarine and sinks the rest of it. Dave begs with Classified to save him, but the latter declares that a good captain must go down with his submarine. Dave childishly insists that he doesn't want to be a good captain and Bruce grabs Dave with his teeth to eat him, but the submarine fully sinks before he can. Smek and the pirates briefly mourn their leader, but he suddenly shoots up into the air and lands in the rowboat containing his crew. Bruce emerges and faces the pirates, this time mistaking the whole crew for fish. He licks his lips hungrily, and the terrified octopi row away from Imagination Land, screaming all the way, with the hungry shark chasing them.
