[30-50 feral rats]

Wait, now you're beating me by another 7.3 seconds?!
... *Twitches*

Well, if I'm going to catch up, I'll have to reduce any time of mine that is more than a second slower than yours. That means Targitzan, Terry, Chilly Willy, Hag 1, and especially Mr Patch.
I could also try Fak Fak the MD9 way, but only after a good few attempts on the five above. Cake!

Edit:
Klungo 2 0:16.30
Targitzan 0:38.70
Mr Patch 0:34.20
Chilly Willy 0:49.60
New Total: 9:25.00

... Mr Patch, sir, I do hate you SO much.
Seriously, Jacky Durand, even by following MD9's example, how did you get less than 30 seconds?! That is madness!
*Kicked into pit of death*

EDIT The second:
Klungo 2: 0:16.20
Klungo 3: 0:19.80
New Total: 9:24.70

Tried Mr Patch, Targitzan and Hag 1 as well, and though I didn't beat my times, I think I've confirmed for myself that MD9's times on all three of these bosses are beatable; he can lose time in several places. As such, I think, if I became good enough, I could beat Targitzan in 30 seconds (if not less), Mr Patch in 27 seconds, and Hag 1 in less than 2:52.00. Though I doubt I'll attain any of those times soon, since my aiming skill isn't good enough atm to match his times. I need a break now.
