It's hardly a quest, just an easy maze. You just keep walking...that's what I did and I made it through in 30 seconds.
Also the rat doesn't have a walking animation, it just glides across the floor.

Yes, there are way too many people on the iPhone server.
But not as many as you see in the screenshots. The noobs crowd around the staff so when the staff post screenshots there's big crowds.

There's lots of long nicks, but there's an option for players to hide nicks on the profile.
