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.
