Grym,
PHoD has you covered on that front
I do dig the slimes though! Any chance of say, some sort of water-y slime and maybe a mercury one? Basically fun with TXIs
... Gotta ask, possible on the Dun pudding to, say, have its texture look like the same when its still, but when its moving have it animate as if its flowing? That was a trick a friend used in WC3 on an Earth Elemental once, though I'm not sure if its completely able to replicate in NWN
