Mystery Box (item)

A Mystery Box is an item found in Paper Mario, Paper Mario: The Thousand-Year Door, and Super Paper Mario.

Paper Mario
The first appearance of the Mystery Box in Paper Mario goes under the name Mystery?. When used in battle, a roulette will appear, containing the following items, that will be used right after the roulette stops on an item:
 * Mushroom
 * Super Shroom
 * Thunder Rage
 * Dizzy Dial
 * Stone Cap
 * A Pebble that hurts Mario with 5 HP

These items can also be used for cooking, but the player must be aware that the item used in the recipe will be random, so the item may generate a Mistake if the player is unlucky.

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, Mystery is sold for three coins at the Sales Stall and the Pungent's Shop. When used in battle, a Mystery makes a completely random item appear that could be anything from a Poison Shroom to an Ultra Shroom to a Shooting Star. If it is cooked with a Point Swap, it makes any recipe.

Super Paper Mario
Mystery Boxes appear under their current name in Super Paper Mario. When cooked, the outcome can be random, or more commonly, a Mistake. However, the set recipe is a Miracle Dinner. The Mystery Box can be bought in Flipside Arcade for five Flipside Tokens, at the Downtown of Crag for three coins, or carried by a Lakitu. Similar to Paper Mario: The Thousand-Year Door, a random item will appear which can be any item from a Catch Card to a Thunder Rage.

Paper Mario: Sticker Star
The Mystery Box was originally set to re-appear in Paper Mario: Sticker Star for the Nintendo 3DS, as seen in early artwork. However, this item was removed for unknown reasons.
