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 chameleon--has to find a way to get it back to him, even if it means crossing paths with a dog or worse, a cat!
