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 third book of this hilarious, highly illustrated early chapter book series.

Oh, no! Noah, the classroom’s evil pet ferret, has stolen everyone’s lunch—and worse yet, he’s done it on a day when Milton’s mom, the class’s go-to super-sub, is off on another assignment.

Will Milton be able to foil Noah’s most fiendish plot yet or will they lose their lunches for good in the gooiest, stickiest, biggest food fight ever?
