Dark Yeti and Pepe. Separated Dark Pepe gives 700exp and Separated Dark Yeti gives 715exp.

Notable Drops Gross Jaeger, Helios, Asianic Bow.
Pros Decent drops for a bore-breaker
Very good money per kill

Cons Crappy spawn
They can hurt a lot if your maneuvering isn't good You have to take out the separated Yeti and Pepe as well

Comments Much worse than their non-dark counterpart, since the spawn is completely crappy compared to Icy Valley II. However, they can also be frozen and the fact that you won't get mobbed too often means that people with a rather low level (relatively, not like level 50 or something -_-") can do some drop-hunting here.
