A Chorus Crime (S03E04)

Unable to decide among themselves which of two strange cases to investigate, the Rangers split up! Monty and Zipper go off to explore the strange ship sinkings by icebergs while Chip, Dale, and Gadget go to find the stolen tap shoes of Canina LaFur, the world's only tap-dancing poodle who was just about to make her big comeback in "Hello Doggy". These two different cases are actually part of the same crime, and the Rangers find themselves working together again to stop nutty Professor Nimnul, who is using tap shoes on a chorus line of penguins to set free icebergs into a shipping lane and salvage the wrecked cargo ships.
