Well, I use to do all that. Now I'm a softy pet vampire to the Slayer and convinced to take you people through this part of Sunnydale, the sewers. Forget about the rats. You need to watch for demons and monsters. They inhabit these sewers.
Oh another thing, watch out for portals. They tend to open down here constantly. If you get sucked into a portal I not going in after you.
Welcome to hellsville. This place is called From High School to Hell. Ride the portal hopping train. Take you anywhere in every universe. Go to Pylea where Lorne, the Host, comes from. They hate singing there and they'll probably use you as a slave. You'll get a new name "Cow" and serve demons. Travel through the mystical realms of other demons that you've never seen before. Need a car for the traveling experience.
