The Flanders Family Tome is a limited-time decoration that was released on October 3, 2018, as part of the Treehouse of Horror XXIX Event.
During the event, it can be upgraded using Incantations. Each upgrade either increases the tap radius of Vampire Minions, increases the rewards from the Old Ruins, or decreases the time between minion clears. The Incantations do not need to be used in order to gain an upgrade, instead they cumulate until the max level is reach at the Tome. It starts with a 24-hour minion clears, no tap radius and no increase in rewards from the Old Ruins.
- Only one can be obtained.
- It can be placed on grass, pavement, dirt, boardwalk, pier, edge of boardwalk, or edge of pier.
- It can also be placed on krustyland path.
