The Zoo Switcheroo (S.O.S.: Society of Substitutes #2)

If there’s a problem in school, there’s no substitute for the world-saving substitute teachers of the S.O.S.! This is the second book of this hilarious, highly illustrated early chapter book series.**

Oh no! Noah—part time classroom pet, full-time evil mastermind—has his paws set on setting free all the animals at the city zoo.

Good thing that when there’s a problem, there’s no substitute for the super substitute teachers of the S.O.S.!
