Yosemite Sam narrates that a low tide and high rocks caused his shipwreck on a small island. After the ship's remaining food stores have been used up, the only source of food is from coconut tree on an adjacent island. Crossing between the islands, however, is always difficult because of a man-eating shark called Dopey Dick (another parody, this time based on Moby-Dick). Sam manages to get rid of the shark, who jumps after him on land, only by having a mallet ready on the tree with which to whack the shark back. On his way back to his island, he's chased again by the shark, but this time has a baseball bat ready to whack the shark. Sam mutters that the shark has tried getting him for 20 years, but misses every time. As a result, one can infer that since the shipwreck, Sam has been marooned
