Perfect Storms (2013)

S1E41 Mermaid Man and Barnacle Boy II

SpongeBob receives an award for his impressive life-size sculptures of Mermaid Man and Barnacle Boy made from Krabby Patties. The prize is the "Magic Conch," a mystical shell featured in numerous episodes of "The Adventures of Mermaid Man and Barnacle Boy." When blown, it emits a sound that summons the heroes, but it's intended for emergencies only. Instead, SpongeBob uses the conch for everyday tasks. Will Mermaid Man and Barnacle Boy become frustrated enough to reclaim the conch from him?
