Hey, I was in the Boreas Seabed (explorable area) and I came across a bunch of these. I happened to be a MM at the time, and I was able to make a minion out of the "invisble corpse" these leave. It may have been a glitch, but is that SUPPOSED to happen?

yes

I suspect that they exploit the 'has a corpse' behavior of resurrects to enable the Zhu Hanuku to resurrect them -- things that don't leave corpses can't normally be resurrected. Yamagawa 03:18, November 1, 2010 (UTC)
