11. Goodnight, Gorilla
If Peggy Rathmann's classic isn't already a bedtime go-to in your home, it will be after the very first reading. A zookeeper makes his nightly rounds, seemingly oblivious to the sneaky gorilla who absconds with his keys and releases all the animals from their cages. The ending will have kids in stitches, as they see where the animals end up, and they'll enjoy adding their own narration to the minimalist text.
