The Emerald Crusade

Weapons/tools wielded by the zealous tree-planting wing of Greenpeace:

• A spring or gas powered gun that fires seeds into the soil. They would have to be coated in a protective substance that then dissolves, idealy providing nutrition in doing so. Name: Seedvolver (Or Peastol if used to plant peas)
  

• A crossbow that fires bamboo sticks into the ground. Name: Bambow.

• A shotgun that fires a cloud of fungal spores. Name: Mushboom stick.
  

This is a sign that I've been listening to too many TF2 weapon ideas.
