Poof

Poof is the baby born to cosmo and wanda. He only appeared once so far in the series in Fairly OddBaby, but he might come back as another main character in the series. Timmy Turner wished that cosmo and wanda had a baby, so cosmo (that's right, cosmo) became instantly pregnant. When Poof was born, the anti-faries and pixies tried to steal the baby, as a baby fairy's magic is uncontrollable. Timmy desperately takes Poof in an attempt to flee, but finds that when Poof laughs, good things happen, when it cries, bad things happen, when it burps, lightning happens, when it hiccups, natural disasters happen, and when it breaks wind, reality itself goes out of control. Eventually, they used Poof's powers against the anti-faries and pixies. They come home to find that it's a boy and name it Poof.
