The Binding of Isaac: The Quarry Collection Boss "A Rock?"

The Quarry Collection is a mod for The Binding of Isaac that recieved some coverage on CZcams before, but this coverage seemed to have been focused on the mod's unique items, rather than its unique and secret boss, which I would argue is probably the biggest thing about it. Thankfully I was able to obtain a recording of this boss fight, and this time, without setting my cheap-ass PC on fire. Thank u/xGoo on Reddit for the footage.

Really sick, it is available for repentance?
