How Samuel, a plush duck, builds a tree house, refusing offers of help from sister Samantha and from the red squirrel who lives in the same tree; how a storm smashes the tree-house roof; and how, after a few rainy days indoors with Samantha, Samuel returns to the tree house to find the damage repaired by tree neighbors Mrs. Chick-a-dee, the squirrel, and several woodpeckers. ""It's fun to do things all by myself--but it's even more fun to do things together,"" is Samuel's conclusion. But Samantha has the best line in ""Ducks don't belong in trees."" Fluff, in the service of banality.
