On a hot day, squirrel brothers Billie and Johnnie Bushytail set up a lemonade stand. A mischievous monkey steals their sugar, forcing them to sell sour lemonade that no one wants. Uncle Wiggily, passing by in his airship, buys a glass but finds it too sour. Hearing their plight, he sweetens the lemonade with his honey, saving the day. The brothers earn enough to buy ice cream cones.
