I have mixed feelings about this book. On one hand many kids find potty humor hilarious. This book also introduces the reader to many different animals. On the other hand we are introduced to a rat who is throwing up, a shepherd holding his sheep upside down in the toilet using it as a cleaning brush and all sorts of pooing and peeing. The rhyming of the book is also off in many places.
The back of the book says, "with a pooping elephant, a farting rhino and a piddling penguin this hilarious book is full of toilet fun." If this is something that would crack you up, I say go for it. The illustrations are good and remain on the polite side of appropriate. If you are trying to potty train your child, this book could either motivate him/her or scare his/her pants off.
