The Insideout Costume was first released in June 2007 in Account Upgrades and the costume has been retired and neglected ever since. A new version of the Insideout Account Upgrade was released in October 2017 with 8 new insideout themed items and either an Insideout coloured Vlad or Tantua Enchanted Plushie. This AU retired November 30th. Putting this costume on a marapet will make it turn inside-out! Insideout pets are red with veins, arteries, and the pet's own skeleton. The opponent Gross is an Insideout monster.
