The special begins with the song “The Perfect Tree,” which features both Mr. Willowby (Robert Downey Jr.) singing about his desire to find the perfect Christmas tree and, within Willowby’s house, a father mouse singing that he will go out to get a tree for his family (his two children, Beverly and Ned, decide to come with him). After the song is finished, Willowby asks his butler, Baxter (Leslie Nielsen), where his tree is.
