Mandrakes

Mandrakes are created by waiting for a Spore Seed to grow. Spore Seeds are produced by Mushrooms starting at Level 8 (Mushroom Kingdom).

Spore Seeds will grow into level 1 Mandrakes (Peculiar Leaf) and through to level 3 (Content Mandrake) without needing to merge. Merging Spore Seeds may result in Spore Seeds or level 1 Mandrakes, but always less than were merged together.

If you merge a set of Mandrakes below level 3, you will NOT receive the expected level 2 Mandrakes; you will create a combination of Spore Seeds, Level 2 Mana Stones, and rarely Diamond-unlock chests.

Starting at level 6 (Kind Tree Stump), Mandrakes can be tapped on an internal timer to produce level 1 Mandrakes, and harvested for Level 1 Haunted Trees (Mossy Log).

Object Information
There are currently 15 levels of Mandrakes, with level 15 being a Wonder.
