Like so many modern families and children, the underwater reef village has forgotten the true meaning of Christmas.

The town is lit up with lights and decorations, and everyone is excited about the good food and presents that are to come. Too focused on these festivities, no one notices that the evil Professor Pinch and his silly sidekick, Clawed, are plotting to destroy the town.

Unwrap the truth of Christmas in Kingdom under the Sea: The Gift as Coral, Splash, the Finley family, and the underwater inhabitants of the reef village turn their focus to the real reason for the season and save their home in the process.
