Well, madder...maderrer...more mad Also IIRC (9 months since I've visited the spot, must go soon
), even the creatures in and around the goo itself - at the far E of the Zorai map for example, are all normal mobs. That is, huuuuuuge ragus, lots of Kirosta, and a nice blue boss kirosta I saw once on the hill. I don't remember anything infected though, even the mobs wandering slightly in the purple stuff Also something for you to note pvtarea
'Hungry' mobs are not goo-infected, they are simply birds 
lol! This list could well be out of date, but I don't remember any 'names' of mobs being switched around Looking at this list and thinking again, there were definitely 'poisened' lumpers near Pyr in beta - they were quite tough too IIRC - and they were aggro towards other mobs, clearing most of the yubos and capryni near Pyr! Maybe it was a mini-event or something - it was mid 04 and I can't quite remember http://ryzom.l9c.org/mobs.php?do=name
Keep searching you will find them
after reading this i am ashamed of the community...no one explores for the infected creatures...no one remebers what they are???i will help spoil this one too...they are a type like hungry or stalking...hehe the infested critters are every where...theres more to this game then just lvl grinding peeps 
i just gave examples of what mobs are...I will never tell what they are...but i will tell you all that it is a mob type if you havent figured it out in 18 months you never will
