Four class pets save the day for their students in this illustrated chapter book. Every school needs a little help now and then, especially PS 1000. Sure, just like your school, PS 1000 has teachers, a principal, and a maintenance crew, who all keep everything running smoothly, but they don't do it alone! Who do you think makes sure everyone gets back on the bus after a class trip? Who doesn't let the scenery in the school play accidentally fall over? Who fights off a gang of rampaging squirrels trying to steal chocolate pudding cups from the cafeteria? The Class Pet Squad, that's who! And when a student leaves his beloved action figure behind in class, the Squad-a hamster, a turtle, a rabbit, and a lizard-have to find a way to get it back to him, even if it means crossing paths with a dog or worse, a cat.
