SpongeBob is looking for Patrick when they are playing hide-and-seek. Patrick forgets that they are playing, so he goes home without telling SpongeBob.
Patrick Not-Star is seen at The End of the World, where SpongeBob mistakes him for Patrick until he turns around, revealing his facial features. Patrick Not-Star realizes SpongeBob's problem of not finding Patrick and overall not winning the game, and says that games are about fun and not winning all the time.
