Big and Small are snowed into the house. Big is happy to stay indoors and read a book, do a puzzle, or play his piano. Small, however, really wanted to play outside and is frustrated at being stuck in the house. To keep himself amused he tries to read the book along with Big, to help Big with his puzzle and to join him at the piano. This is annoying for Big, until he realizes that Small's musical contribution is actually helpful for his latest composition. And they find themselves writing a really great song together. Now they can play in the show tomorrow.
