The Prisoners


The prisoners first appear inside of a boat. SpongeBob tries to amuse them but fails to do so. They then arrive at the island where they do very dull activities that SpongeBob and Patrick feel are fun. Afterwards, they decide to set up a play with SpongeBob and Patrick but they use it to sneak out of the island.
