Part 3

A purple submarine door with a life preserver is shown, then Patrick Star appears with a wide-eyed expression, followed by a shot of Patrick and SpongeBob SquarePants looking out the door, then the door closes and Patrick's hand is seen pushing it shut, after which Patrick reappears with a different expression, and finally a bird is seen flying in the sky. The setting is underwater, inside a submarine, and in the sky.
