The Mystery Box (initially called Revised Mystery Box) is a consumable introduced on April 1, 2015, which gives the player a random item. It replaces the original Mystery Box and can be obtained by buying it for 6 Donuts in the store. It is also available as a reward from the Daily Challenges System.
The prizes from the Mystery Box were much better than the ones from the original Mystery Box. A list of all available items and the chances to win them is provided below. The presented chances may vary if the player already has some or all of the unique items (Blue Haired Lawyer, Kearney, Jimbo, Squeaky Voice Teen and the Tire Fire).
When the Mystery Box was first released, one was given to players for free if they had Mr. Burns and if they logged on before April 30, 2015.
Mystery Boxes could have been obtained from the Daily Play Combo. As of February 4, 2016, the Daily Challenges System replaced it and players are occasionally offered the chance of completing challenges for a Mystery Box.
This box is sometimes referred to the "Revised Mystery Box" to avoid confusion for the original Mystery Box.
