Hornedtail Fake heads

There's no need to apologize, I've made the same mistake before and looked just as foolish (which is why I try to avoid responding unless I'm knowledgeable of the topic subject).

The left and right preliminary heads that you fight could be compared the arms of Zakum, they're just a warm up and a duo is certainly possible, though I personally wouldn't feel like spending so much time doing something so unrewarding.
