When Cory returns from his morning walk-about, he overhears an argument between Adam Mouse and Thelma. These two friends vehemently discuss that the days are getting shorter.
Trying to defuse the situation and restore tranquility to the ditch, Cory sets out to demonstrate the rotation and tilt of the earth, using Thelma as the sun and Bunny as the earth. Bunny holds a stick close to her chest, the a stick representing the earth's axis, and her nose representing where the friends live.
With Rudy Raccoon holding Bunny, Cory asks Rudy to stop at winter, spring, summer, and fall. Then he asks Adam and Beetle where is Bunny's nose?
After the demonstration, Thelma had to admit that the days were getting shorter and apologized to Adam.
In the next chapter, the friends scamper off to collect fall leaves, and learn why the leaves change colors.
