Rainbow Fish

Sea Filly the Sea-horse, comes to the school of fish, and Rainbow and his best friend Blue, welcome her in.

Rainbow is excited to meet his hero, renowned hockey star Wayne Grunion when he comes to town for a visit.

In the school band, Mrs Chips gives Rainbow Fish the conch shell, the hardest instrument in the band to play. Rainbow is then forced to practice, and he does so, gradually making for a better performance at the school concert.

When Rainbow Fish and his friends attempt a dangerous sport called "Riptiding", Blue is swept away on a riptide, and Sea Filly and Rainbow must find him before it's too late.

Rainbow Fish gets a bad report card (he gets a "C"). But when he accidentally spills ice cream (from a kelp gusher milkshake) on it at Wanda's, his parents mistake the "C" grade for an "A". Rainbow must prevent them from meeting Principal Gefilte and learning the truth. For getting a "C", changing his grades, and lying that he got an "A", he is cave grounded by his parents until he gets his grades up. This means until he gets his grades up, he is "cave grounded" except for school (meaning he can only leave the house to go to school while cave grounded).

Rainbow is not enthusiastic about spending time with his grandpa while his parents are away at the store, thinking that he will be bored, but when his grandpa tells him an amazing story that hides an incredible secret, Rainbow discovers that old people can be exciting after all.
