Tanny Fanny is an elixir available at Slurps and Burps. It affects the user by giving their skin a darker, tanner complexion. Sophie used it in Neverseen in order to disguise herself as to not be recognized by the Council during the gnomes' protest and Fintan's disruption. Much like other appearance elixirs, it has a bad taste (Tanny Fanny is said to taste like rotting garbage) to prevent the user from using it too often.
