Hit the Play button and the Hungry and Thirsty monaters for your pet will change to 1. When you want to change those back to zero you click on the food or the drink then to get your monkey back on the rock you just click the monkey. With this fun game you can have your very own virtual pet. When you are done playing with and feeding your pet just hit the red stop button at the top to put your pet to sleep.
I used the step-by-step on the Tips.
