Aaron is a Good Sport(2015)

P.D. Eastman

P. D. Eastman’s classic character Aaron the Alligator makes his early-reader debut! Aaron can get into trouble doing just about anything—playing ball, planting seeds . . . even walking! Kids will giggle along as they tackle the simple words and sentences all on their own. Aaron is a star of The Cat in the Hat Beginner Book Dictionary and a long-out-of-print series called Everything Happens to Aaron.
