The episode begins with SpongeBob wishing he could fly with the jellyfish. He makes several attempt to do so, including a biplane (which malfunctions and destroys Farmer Jenkins' grain silo), bat wings, a garden chair with balloons, and a giant kite pulled by a bicycle. After his failed attempts are witnessed by others, he becomes known as "The Birdman of Bikini Bottom" and is ridiculed. He tells the people that "it is a sad day in Bikini Bottom when a guy is ridiculed for having dreams!" The townspeople tell him that they all once had unfulfilled dreams, then proceeding to form a mob and start chasing him for thinking he is more important than them. SpongeBob runs off a cliff and falls into a truck of mud, then into a truck of feathers, much to his misfortune.
Later on, SpongeBob is shown in his house, having given up on his dream. He begins to dry his hair, then he receives an insulting phone call from a "fan" of the "Birdman," namely, "Joe Momma." SpongeBob puts the hair dryer in his pants while he talks, and the dryer inflates his pants, giving him the ability to fly. He goes around helping people, earning their admiration and becoming a superhero of sorts. However, the lazy citizens continue to ask increasingly unnecessary favors of him, leaving him no time to fly with the jellyfish. When he tries to escape to Jellyfish Fields, the people form a mob and chase him, but are unable to catch him. However, Cannonball Jenkins blasts SpongeBob, destroying the pants and sending him plummeting to the ground. The people seem as though they are mourning SpongeBob's death, but they are actually mourning the inflatable pants.
SpongeBob is about to go home, but suddenly, the jellyfish help him fly. They take him home as he sings an intentionally corny song about how all you need to fly is friendship. As he says goodbye to the jellyfish, Patrick greets SpongeBob and offers him a trip to the Pizza House. SpongeBob declines and leaves it up to the jellyfish for flying. Patrick then says "Suit yourself" and flies off like a superhero does. A confused SpongeBob wonders if Patrick just flew, only for him to doubt it because of how silly and impossible that seems, the episode ends as he looks at Patrick out of curiosity.
