Colin the Crab spends the whole week helping his friends. He needs to build a new house for the fish family to replace their collapsed one. Sally the Starfish and Eddie the Eel also keep Colin busy with their requests. Feeling exhausted, Colin locks himself away in his house, and his friends are baffled. How can they cheer him up? Perhaps it's time to work together, have some treats, and take out Ms. Catfish's old gramophone. Even a helper needs a little rest sometimes.
