The shim-sham-jimmety-jam-clapper-gapper is an item from Freddi Fish 3: The Case of the Stolen Conch Shell.
The shim-sham-jimmety-jam-clapper-gapper is first seen when it keeps popping out of Horst Fedders bag, much to his annoyance. When Freddi Fish and Luther uses the foregin language phrase book to translate Horst's native language depending on what flag is on his bag, they ask him if they could borrow it. Horst happily gives the gadget to them since it was giving him so much trouble. Freddi and Luther later uses the gadget to get the golden pipe out of the clam's mouth. Once the retrieve the pipe, the clam eats it whole.
