This is a company that Timmy, Tootie, Cosmo, Wanda, and Poof opened up to help others around the world by using magic, and help Timmy keep his fairies. To disguise the fairies, Timmy buys a pink van for their business.
At the conclusion of the Fairly Odd Movie, Timmy decides to grow up and give up his fairies in order to save their lives. However, due to acts of selflessness by Timmy during the movie and times past, the Fairy Council creates a new rule that allows Timmy to keep his fairies, so long as he uses them for unselfish needs. Tootie, who also discovered and learned of Timmy's fairies, is also allowed to learn of them and share in Timmy's secret, being that she was the one who helped teach Timmy to wish for others rather than himself.
Reunited with his fairy family, Timmy and his new girlfriend Tootie return to Earth where they opened up a business called "Wishful Thinking", hoping to use the Fairy Magic for good purposes around the world. They travel in a flying pink van and use the business as a disguise for the fairies.
