On October 25, 2012 at Josie's, Zed asked Evan "How will we write a mouse story?" And here is what Evan said:

Mice are little, tiny creatures. Their tails are small and they are not like a ball. Mice are not pests. Mice like eating. Mice are tiny creatures with noses that are tiny. Mice whiskers are white. They have tiny feet. Mice are tinier than your foot. Mice are adorable.
