Uncle Wiggily’s Automobile [PDF ebook] 
(Illustrated Edition)

Uncle Wiggily is a series of sweet little animal stories, sprinkled liberally with corny made-up words and very typical of the times. Each individual story is short enough for bedtime, and the readability level is perfect for the reader transitioning from simple to chapter books.
Uncle Wiggily is told to spend more time outside exercising by Doctor Possum and so he spends time every day driving around in his automobile having adventures.
