"I'm a Rock" is a song from the Muppet Treasure Island sing-along video.
Bad Polly is knocked into the ocean following his song "Old Bad Polly." He lands on the ocean floor, where some singing clams call him a "soft-shelled crab." Polly insists he's hard as a rock and sings about how tough he is. A shark swims by and also challenges his strength, leading to a brief case where Polly gets caught in Clueless Morgan's lobster trap (as the clams gurgle Chopin's "Funeral March").
