Colin the Crab, the most skillful builder on the eastern riverbank, never hesitates to help his friends. Now Colin is busy with his own new project-a garden pavilion for his home. But after a week of hard work, the pavilion of his dreams is still unfinished. Even worse, a boisterous fish family has taken over the construction site. The exhausted Colin buries himself under a blanket and refuses to open his curtains. Puzzled, Colin's friends call an emergency meeting-it's time for them to take action!

Krabis Kristofers - austrumu krasta meistarīgākais celtnieks - nekad nekavējās palīdzēt saviem draugiem. Pēc nedēļu ilga smaga darba, viņa zilais sapņu dārza paviljons joprojām nav pabeigts, un trakulīga zivju ģimene ir pārņēmusi viņa būvlaukumu.

Pārgurusais Kristofers ierokas zem segas un atsakās atvērt aizkarus. Kristofera draugi ir neziņā. Tiek sasaukta ārkārtas sapulce. Draugiem ir laiks iejaukties.
