Mouse has built a lovely new house. But as he stands outside to survey his handiwork, he notices one window is a little crooked. His friend Bear offers to straighten it. Except, in the process...he pulls it off the wall. Fortunately, Squirrel passes by and offers to fix it. Except, in the process...he breaks the pipework and causes a flood. And so it goes on until Mouse's house completely collapses under the weight of all this help. Mouse's house is ruined! What will he do now?
