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!

Rakec Misko, najbolj spreten graditelj na vzhodnem bregu reke, ni nikoli okleval, ko je bilo treba pomagati svojim prijateljem. Po tednu dni trdega dela, pa je bil njegov sanjski modri vrtni paviljon se vedno nedokoncan, in razposajena ribja druzinica se je igrala na njegovem gradbiscu.

Misko, izcrpan od trdega dela, se je zakopal pod odejo in ni zelel odstreti svojih zaves. Miskovi prijatelji so bili zbegani. Sklican je bil nujen sestanek. Za njegove prijatelje je nastopil cas, da nekaj ukrenejo.
