The Creature Slaughterdome is a good place to look for a Chubby. My friends and I found a few in there. I, however, got the achievement before I reached level 10...
As for Donkey Mong, I found him twice by Mal (The robot in the "Real Boy" side quest) on a ledge below his hangout.
I know this isn't Jenkins related but I thought I'd help
I've been trying the Opportunity one for about 20 minutes now and I got 2 mini loaders...Jenkins is the last pain in the ass challenge I need to do D:
