A group of animals discovers a large, round, orange object with a green stem and begins to question and surmise its usefulness and possibilities.Squirrel and Field Mouse push it out of the way, and it rolls to a stop where Opossum is napping. Opossum thinks it makes a rather comfortable chair. Raccoon is sure it is a table to support a plate of cookies. Soon others join in to enjoy the cookies and cider, which Opossum contributes. While the impromptu party is in full swing, Woodchuck explains the object would make a good doorstop. As day turns to night, Skunk professes that it's really a lamp and demonstrates how to carve it out and place a candle inside the now-smiling face. The pulp and seeds are then used for pie and roasting, which everyone snacks on till they hunker down for winter. When they emerge in the newly verdant spring, they discover a plant that produces a flower, which then becomes an orange, round object and…it's party time again. These unclothed but otherwise anthropomorphic cartoon creatures never actually say the name of this autumn gourd, leaving it to kids to express the obvious, only acknowledged in the title. The somewhat lengthy text spins out its premise deliberately, and kids who know very well that it's a pumpkin and what a pumpkin is for may tire of the speculation, but the community interactions are charming to watch.Curiosity and ingenuity in a mild fall mystery.
