Patrick is Spongebob's best friend. He is less keen than Spongebob, but often has brief moments of rare insight. Patrick cooks up crazy ideas that often get Spongebob and himself into a mess of trouble. He fancies himself quite the jellyfisher, and loves many of the same things that Spongebob loves. He was born on March 14, 1983. He lives under a rock on 120 Conch Street, 2 doors down from his best friend. He really likes balloons and ice cream, but is very scary when provoked. He also wakes up at 3 AM to eat Krabby Patties.
In the earlier episodes, he simply wears his trunks to bed. Later on in the show, he wore a pajama outfit. The newest episodes, including the episode that showed his 3 A.M. habit, have him wear his briefs to bed like his friend Spongebob does.
