Peep says it's time for Egg to start using the potty. But Egg does not want to use the potty-and no amount of lemonade-drinking, running water, or toilet-paper tutus can change that! When things start to get a little uncomfortable, Egg realizes that when nature calls, sometimes you can't say no. This fourth book in the Peep and Egg series will be relatable to parents and children alike.
