How to open locked door to Frifle and the Grey Mauser?
I discovered Frifle and Grey Mauser in the gungeon behind a locked door. The door itself has eyes and highlights when you walk close as if you can interact with it, but doesn't unlock with a regular key.
When you interact, the door's eyes react as if I'm missing something, but the door doesn't speak or offer an obvious challenge. How does this door open?
