Lu The Explorer/I've Got Rhythm?

Splash takes his pals to go see his friend, LU, a fearless explorer in the deep. He has met Lu in his travels, and she has been an inspiration for Splash. Lu turns out to be a female football fish (the 'Lu' stands for 'bio-LU-minescent') who leads them on an adventure in the abyss. / Wave, the octopus, loves the musicality of Reeftown, but tries to keep others from discovering that he has no rhythm.
