Costume Bag (Retro)

It was introduced to celebrate Tibia's 20th Anniversary. Rewarded from Vigintia's can knockdown minigame, bronze category.
Using it will give you the appearance of one of the following:

• Giant Spider (Nostalgia);
• 3478;
• Bug (Nostalgia)
• Wolf (Nostalgia)
• / A character wearing the original sprite of one of the outfits introduced with Updates/7.0.
  
  It can last for approximately 5 hours. Note that you'll lose your costume if you go swimming, become invisible, get your appearance changed by a creature such as a Dark Apprentice, use a Chameleon Rune, die, use the spell Creature Illusion, use a Spellwand on yourself, or transform into a corpse for a few seconds (e.g. when passing out on mead). Also note that you won't be able to use a mount while you are transformed.
