Annoyed at Flapjack's constant noises while he is trying to sleep, K'nuckles tells Flapjack about the curse of Mute Mike and accidentally curses Flapjack with the inability to speak. They go to the Knot Festival to try to find a cure for his curse. They go around trying to find cures, until K'nuckles hears Flapjack speak. K'nuckles becomes angry when he realized that Flapjack had the ability to speak all along, merely faking it so K'nuckles would take him to the Knot Festival. K'nuckles asks Flapjack to cover his ears while he uses "strong language", which earns him a trophy. Flapjack finds a Singing Booth, and starts singing songs. He sings for so long that he eventually truly loses his voice. When they return, K'nuckles exposes Flapjack's lie to Bubbie, though she doesn't believe him, and he gets brutally stung by a large group of jellyfish that she had recently swallowed.
