Poof Cosma is Cosmo and Wanda's baby son from the Nickelodeon animated series The Fairly OddParents. He was born as a result of a wish that Cosmo and Wanda's godson, Timmy Turner, made in the premiere episode of the show's sixth season.
Appearances in Christmas specials
The series' second Christmas episode, "Merry Wishmas", marks Poof's first appearance in a Christmas-themed production. Ironically, despite the episode being set during Poof's first Christmas (as well as his second, because it takes place over the course of a year), he does not have much baring on the plot other than helping his mom and dad deliver the Wishmas coupons to all the kids in Dimmsdale.
Poof has a somewhat bigger role in the live-action film A Fairly Odd Christmas, which takes place approximately thirteen years after the events of the original series. As it is a sequel to the series' first live-action film, Poof and his parents have been allowed to stay with the now-grown-up Timmy and his girlfriend, Tootie, thanks to a "Timmy Turner loophole" added to Da Rules. The film finds Poof accompanying his godbrother to the North Pole on his journey to find Elmer the Elder Elf, who can take Timmy's name off the Naughty List. Like his parents, Poof does not get along well with Santa's elves, particularly Dingle Dave and Christmas Carol, due to the fairies' feud with the elves. At one point in the journey, when the group is crossing a rickety bridge over a boiling eggnog river, Poof uses all the strength he has to keep Timmy on the bridge. At the very end of the film, Poof, in a rare moment of speaking, says Tiny Tim's famous line, "God bless us, everyone!"
