Burger Beard, referred to as Painty or Captain as a painting, is a pirate captain with a reddish-brown beard. A painting of him appears at the beginning of the show's opening sequence. He sings the SpongeBob SquarePants Theme Song.
Burger Beard starts by stealing the Magic Book from the guardian skeleton on Bikini Atoll with the intent of rewriting the story of Bikini Bottom life in order to gain the Krabby Patty secret formula. Once gained, he travels to land to sell Krabby Patties from the Burgermobile.
"Truth or Square" is the only time that this painting has appeared without his parrot.
His dummy version is much different than his painting.
It should be noted that while Burger Beard was transformed into Painty the Pirate at the end of the movie, it is not confirmed if they are the same character, or if this is simply a way to transition into the rap battle.
