Orange Door

The prince goes through the door and sees what awaits him. He looks around and is a bit weirded out. There are a bunch of weird penis monsters of sorts roaming this place, some even on penis horses of some kind.

Then you see a castle of sorts in the town and think that’s where the ultimate power is.

1.) Get caught by two penis guys

2.) Go to town and see the weird looking locals.
