S3E30 The Sponge Who Could Fly

SpongeBob dedicates himself to creating a device that will enable him to fly. Despite his numerous attempts, his inventions fall short, leading others to label him as crazy. In a moment of inspiration, he decides to stuff a hair dryer into his pants, and the hot air lifts him off the ground! However, his newfound ability quickly turns into a burden as townsfolk begin to request his help, preventing him from enjoying his time soaring with the jellyfish.
