Once you get your very own Foofa living in your mobile phone, you can visit it any time you want. And when uncertainty or curiosity about something starts to bug you, all you have to do is think of a Yes or No question and give the little guy a little shake. During this process, the Foofa receives your vibrations through the mobile device, visualizing your question. Once it stops shaking, the Foofa will answer your question, and you can trust that it is telling the truth. Sometimes the Foofa might get a little confused from all the shaking - no problem, just give it another, bigger shake, and it should be fine.
