The Vortex Costume was a Costume that was part of an Account Upgrades set in January 2009, but has been retired and forgotten about ever since. Marapets has updated and renamed the costume; the Tornado Costume's Account Upgrade was released with 8 new tornado themed items, including the Vortex Park Reservoir Treasure Map, which was the main prize. It retired on July 31st. As a result, the Vortex Park Reservoir Treasure Map will not be released again for several years. If you put this on your pet, they will have a tornado right behind it, be stuck in it, or be riding on it. Tornado pets are grey and the costume has a tornado with a Grey Costume. The Costume also pays homage to the film The Wizard of Oz.
