Aye, it's exactly that. To expound on the names..
The 150-200 zone mobs go in this order:
Pustulous
Seeping
Foaming
Revolting
And the 200-250 zone mobs go:
Demented
Frenzied
Fiendish
Lethal
They drop as many meats as is their rank in the zone (so Foaming will drop three meat, be it plant or animal), while a Pustulous or Demented one will only drop one meat. The Revolting Gingos I've seen in Knot of Dementia, for some reason, are only in their 130s, so they drop four meats, but are only worth two merit badges per meat. Pretty easy to kill though, for lowbies, as they patrol on their lonesome.
