(Netflix)

In this musical special, the Octonauts must find a way to hold back hungry swarms of coral-eating starfish to save a new friend’s fragile reef home.

FUN MUSICAL FACT

Castanets are on the short list of things to invest in if you’re going to write for kids’ TV. Sooner or later, there will be crustaceans (also on the list: sleigh bells, birthday horns).
