What good are they doing? Nothing. Nothing but a bunch of dirty hippies rolling around killing mother earth's plants.
If you listen very carefully, you can hear the plants screaming in pain. One even rolled on one of their offspring for god's sake! Sickening..... those plant killers.
And what of the bugs they killed. I'm going to scream for them too.
WAAAAAAAAHAAHHH. WAAAAAAH! WWWAAAAAAH!
Oh, I feel better now.
