Planting trees with prejudice and force.
Comes with:
- A tree shotgun for precision tree placement
- A cluster grenade for faster forestation
- An "acornic bomb" for indiscriminate mass forest creation

The method of tree selection works in a handful of ways:
- "Heavy" mode is more expensive, but is the closest to initial map generation
- "Light" mode is a less expensive approximation to initial map generation, and is more likely to spawn different trees
- Pipette selection override (for when you want to plant a specific tree)
- If none of the above options find a tree to use for whatever reason, a "use last tree" option

Acorns drop from trees with a low drop rate. A "seed duplication" tech is unlocked at green science.
If using Angel's Bioprocessing, these acorns are replaced by the generic trees provided by that mod.
