Colin the Crab has many special friends at his home in the river bay. It's hard to imagine anyone more beautiful than Sally the Starfish or more successful than Eddie the Eel. Ms. Catfish's antiques are very impressive, and the big newt family is always busy and full of energy.
Just as Colin starts to wonder if his own life is a bit too ordinary, a tidal wave tosses Priscilla the Pearl Oyster into his backyard. Colin's new friend has something very valuable--something that many others want, including the deceitful Larry the Lobster.
