Starting the quest
We've got to figure out the deal with those Mutant Hedgehogs. How have they multiplied so quickly?
It's imperative that we be aware of what's going on in the area around our hideout.
So, your next mission is to investigate the Mutant Hedgehogs. Think you can do it?
Reply to “Yes”
I want you to bring back some 
Mutant Hedgehog Fur items. If we study them, we might be able to understand the sudden population boom. 5 of them should be enough.
Reply to “No”
What, do you have something more important to be doing?
Turning in the quest
Did you gather enough Mutant Hedgehog Fur items? Then hand 'em over!
Reply to “Yes”
Huh! The non-spiny sides of these Hedgehog pelts are pretty soft!
That's right.
Granted, that's hardly a scientific assessment... For that, we'll need somebody else. And I know just the guy.
