Who Pooed in My Loo?

In the bathroom this morning, I looked in the loo, and guess what I saw-yes that´s right, it´s a poo! I couldn´t believe it, I called for my mum, ´There´s a gift in our toilet that´s made by a bum! When a little boy finds a poo in his family loo, he starts imagining who might have left it there. Was it ... A dragon? A unicorn? A dinosaur?! With every idea more exciting than the next, he can´t wait to find the culprit. But who could it be?
