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.
