Lenny sets off to track down the source of the nasty niff . . . Along the way, he meets lots of stinky creatures, finding out about the different smells they make and why.

Learn about sloths, skunks, stinkbugs and more in the whiff-tastic Poo! Is That You? written by Clare Helen Welsh and illustrated by Nicola O Byrne. Cleverly interweaving facts throughout, it also contains an information page at the back of the book, with a photo of each animal.
