Trigger steals the file Sam the Sawfish uses to sharpen his nose. When Trigger shows the file to Baron Barracuda the two villains are startled when they see the tool flying through the water until it is stuck on a large rock. When Sam swims by looking for his file, his nose becomes attached to the same outcropping. Baron deduces that the rock has some mysterious attraction to metal and decides to lure Diver Dan into a trap by tickling Sam until he calls for help.
