For fans of The Sour Grape, here is a laugh-out-loud picture book about resisting the temptation for revenge—and why it’s rarely the answer.

Mushroom is having a bad day . . . okay, maybe that's an understatement. Mushroom is having the worst day EVER. First, he's not picked to go on the pizza (and Pineapple is chosen instead of him—can you believe it?! PINEAPPLE!). Then, Milk spills all over him. Just when he thinks it can't get any worse, he's thrown in the compost bin. What else is a mushroom to do but build an army and take revenge?!

Becky Davies's hilariously outrageous text and Thomas Elliott's expressive and laugh-out-loud illustrations pair perfectly to teach little ones an important lesson on revenge, kindness, and managing emotions.
