Your friend was messing with you or he was high on some shit. Congalala can hold a bone in its tail instead of the usual mushroom.

A bone, yeah, like the kind you see a dog chewing in a cartoon. I don't recall it ever having a skull. Hermitaur and Ceanataur wear skulls.

So I have a friend that claims congalala can hold and eat a skull instead of a mushroom and go ballistic, though I have never heard or seen anything about it, and I can't find any info about a congalala eating skull online other than that it can hold a bone instead of a mushroom. So i'm wondering if my friend is crazy or if no one ever bothered to talk about it.

Congalala holding a skull?
