Cubi battle? I haven't seen one but maybe this is what it looks like. Also, I saw something like this when I youthened a pig and again when I fed it and it grew up.

Yes, cubi battle. I don't know why people habitually park the battle behind that tree. But every one I've seen so far has been unwatchable because of it.

Cubi battles are hysterically funny! You should do one in your house so you can really see what's going on! Their insults are quite imaginative.
