The Mushroom of Doom by Becky Davies

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. And then he's thrown in the compost bin. The indignity!
I know exactly what you're thinking . . . it's time to build a mushroom army and take revenge!

A laugh-out-loud picture book with the message that revenge never pays.
