Okay, you have got to read this. This is awesome. It also proves how cruel I can be...
When you arrive on the Oppel farm, first locate the giant crusher. It's the giant structure that activates with a Zappfly switch . Now, stock up on Chippunks (you will need to do this many times after this too).
Now switch your ammo to Chippunk and Zapfly. Fire a Chippunk into the center of the Crusher (or just inside it) to lure your first victe--er,
Clakker into the crusher. While he/she's distracted, target the Zapfly switch and fire a shot at it. The Clakker screams as he's pulverized into tiny Clakker bits!

HAHAHAHA!
Clakkers who are farther away will need further coaxing to get them to the Crusher.
I just thought I'd share this game spoiler, since the Oppel farm is the only community in the game where you can actually kill the townfolk.
Have fun, you horrible, murderous people you!
