You can't comprehand the size of these guys until you've seen them. They dwarf rancors. I have one in my house a s a deed and a rancor too and the kimo's big enough for me to move the rancor on top and make it look like it's riding it.
hmm yeah on lok last week i noticed 2 wild gurk lairs next to eachother one was "a nest" the other was "a thicket" but both had the same girks spawn from them. i dunno thought i mention it.
