In "Pizza Delivery," we meet Piper's father for the first time. In the series, he is the only father we ever meet.
In this episode, both "Museum Mouse" and "Pizza Delivery" use a piece of clay as the main object for launching the stories. In both cases, the characters have to come up with creative solutions, not just for creating art, but for solving problems.
Mouse and his friends are very good at creating their own world, reflective of the adult world around them - such as in "Museum Mouse," where they create their own art museum. This is the type of play that is key for the development of our young viewers.
The museum location design in "Museum Mouse" was inspired by the architecture of the American Museum of Natural History in New York City.
