Sam, Sebbie and Di-Di-Di & Xandy: Return to the S.E.A. Aquarium - Sam, Sebbie and Di-Di-Di, #7

It's Xandy's birthday and the family is celebrating at the S. E. A. Aquarium Ocean Dreams overnight stay. They are all excited about the birthday party the next day, but there's just one problem. Everyone forgot the party decorations! Sam, Sebbie, Di-Di-Di and Xandy set out to search for decorations and encounter many friendly and amusing sea creatures who try to help. They meet responsible sharks, clueless eels, beautiful sea jellies, helpful leafy sea dragons and amazing star fish.
Will their new friends be able to help make the party a success?
