Population reduction: Stumpers

Eliminate the Stumpers in the Green Pigweed

Stumpers are perhaps the most dangerous creatures on Eden. They're strong and almost invulnerable to our firearms. With their population as big as it is now, we can't feel safe in this world. We need to reduce their numbers.
Why don't you take care of it? I'll show you where our scouts found the greatest number of these creatures.
Kill as many as you can! No pity! Stumpers will surely show none to us!

The fewer of those creatures, the better.

I believe the local animals have been breeding faster than ever since your arrival at Eden. Felix suggests eliminating them before they eliminate us!
