One day, SpongeBob wakes up and begins playing fetch with Gary, leading the snail to dig up a treasure chest. SpongeBob opens the chest and finds a magic bottle, which, upon rubbing it, releases doubloons all over Bikini Bottom and releases The Flying Dutchman. The Flying Dutchman tells SpongeBob that he will take Gary to work on his ship for all eternity; after briefly leaving to check on his ship, he makes good on this promise. (wikipedia.org)
