There's now also corrupted Gibbaï just west of Knot of Dementia Karavan altar.
Also, I was mistaken about the last Goo infestation in Witherings. There were in fact mutated (stronger than normal) forms of Kizoars, Torbaks, Najabs, Igara and incredibly huge Gibbaí. And they popped up much more quickly than in the Verdant Heights infestation too, maybe because the Witherings already has a lot of Goo.
I didn't remember because we never had to clean them out, they went back into the Goo on their own.
No, I've never see a Goo infestation come in waves.
