I need a new bum! Mine's got a crack.
I can see in the mirror a crack at the back.
What to do when you need a new bum? Should you get one that's blue
or yellow spotted? A rocket bum that's all fire and thrust, or a robo-bum?
The options are endless – but wait, Dad's bum crack is showing too? Maybe this is contagious.
Certainly it is for readers – I Need a New Bum! has been in the NZ children's bestseller lists for years, and it reprints at least annually. Meanwhile it has been a regular on bestseller lists in the US and UK, with hundreds of thousands of copies sold.
