'Who's in the loo? There's a very long queue. Is it an elephant having a poo?' If your house has many occupants, then this witty rhyme from the irreverent and observant pen of Jeanne Willis will resonate profoundly. Adrian Reynolds's exuberant illustrations highlight the fun!

Two children who desperately need to go try to figure out why there is such a long line for the bathroom.

Knock, knock! Who's on the loo? Lift the flaps to find out in this hilarious board book featuring spotty, stripy and colourful animals on their matching toilets. Delightful rhyming text and funny illustrations will make this bright board book appealing to preschoolers and parents alike. Every animal, from Zak Zebra to Tilly Toucan, once revealed under the flap, gives out some advice about how to use the bathroom that will serve as great reminders for children who have mastered the potty.

Lid up, pants down, bottom on the seat! They must not have toilets in outer space, because this baby Martian keeps going in the wrong place: a bird bath, a bin, an up-turned hat. Perhaps if he masters "The Toilet Song," he might learn where to go.

Hippopotamus had a spotamus . . . on her bottomus! "It's a blister!" said her sister. "It's measles!" said Weasel. "It's hippopox!" said Fox. But in the end the spotamus turns out to be something hilariously unexpected!

Children who have reached the toilet-training stage will think this is the funniest book they've ever seen! Parents will smile, too, as children and parents turn the pages to discover who's on the loo. The colour illustrations are large and bold, and the story concludes with a flush sound button for children to press. A little duck watches as several animals take turns sitting on the toilet accompanied by amusing text - a gentle encouragement to toddlers who are toilet training. The book's final two-page spread features a pop-up showing all the other animals shouting 'bravo!' as the little duck flushes the toilet.
