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! ----- Krab Colin, najzručnejsí staviteľ na východnom brehu rieky, nikdy neváhal pomôcť svojim priateľom. Po týzdni tvrdej práce jeho vysnívaný modrý záhradný altánok stále nebol dokončený a hlučná rybia rodinka zabrala jeho stavenisko. Vyčerpaný Colin sa zahrabal pod deku a odmietal odostrieť svoje záclony. Colinovi priatelia sú zmätení. Je treba zvolať mimoriadne stretnutie. Priatelia sa rozhodli konať.
