Going Batty #32

When Katie sees toy bats hanging from the ceiling of class 4A, she thinks they're Halloween decorations until Mr. G shows up and explains the class is going to study nocturnal animals. A visit to the zoo starts out way cool but quickly goes downhill: Suzanne and Becky won't stop fighting and then Katie finds herself hanging upside down inside the Bat Cave. Katie has really gone batty this time!
