The one-part quest is given by Emile, the Farm Girl.
We've got a problem. The town's infested with these crazy, hiding, vicious plants. Never seen nothing like 'em!
- Defeat 10 Carnivorous Arnoldii. (Skip for 10 each.)
I guess you dealt with the problem. I'd be OK admitting that I planted those things. I didn't mean to! I must have grabbed the wrong seeds off the shelf.
