Okay it's the sewer rats in the opera house. If you be patient and don't fight one in the opera house, it'll still be there in the WOR, then if you go fight then, and kill yourself, you'll end up in front of the opera house in the WOB with no way of getting back. Pretty funny glitch eh? It's only available on some cartirdges for the SNES. I tried it on the PS version and it doesn't work. But yeah, sewer rats. Alienator is the closest since it does deal with fighting ultros in the opera house kinda. If I get another chance, I"ll get on that'll be a little more known
