Mmm, delicious! Polly and Pim are enjoying the banana. But what happens to it next? Together, the two siblings follow the exciting digestive journey of the banana through the little poop factory: from the first bite to the banana-shaped poop in the toilet or potty. With over 230,000 copies sold, "The Poop Factory" is a huge hit among all the big and small know-it-alls. Newly redesigned but just as funny and straightforward, "The Little Poop Factory" now also explains to the tiniest ones in a simple and visual way what happens during digestion. Going to the toilet or potty becomes especially fun!.
