"Calypso" is the coach for "Tusa" as it was featured in Just Dance Unlimited as well as a minor character in the franchise's lore. Calypso is one half of "The Sovereigns of the Seas" together with her fiancé Triton. Born as a princess from an unknown kingdom in Melosia, Calypso has a deep fascination of the seas and was taught by Triton how to dive and dance. She was gifted with golden shells in their last meeting before they part ways, allowing her to listen the sea waves when she wants to. She first appears in Randomized Hunger Games IV.
