Watch Shaggy Throw a Kriller Ocean Celebration With His "Under the Sea" Performance

Down here all the fish is happy, especially when Shaggy is playing Sebastian the crab. The 51-year-old musician performed Disney's famous "Under the Sea" for The Little Mermaid live production on Tuesday night, and quickly turned the whole stage into an ocean celebration. Shaggy didn't wear much of a crab costume (unless we count the all-red ensemble) but what he lacked in claws, he made up for in energy.

Auli'i Cravalho's Ariel floated along as all the fish of the ocean — creepy Flounder, included — swam and danced their way through colorful choreography. There were even aerial dancers, erm, I mean, jellyfish, twirling above the audience. A sea-riously detailed performance, indeed! (Sorry, I had to.)
