If you go to the lighthouse monorail and go backwards you'll pass by a door with a lever next to it, open the door and you'll find a big hallway and a main room, the main room says "Funland Inc. Administrative Offices" If you go into the hallway you'll see multiple rooms, i'm only going to talk about a few important ones, The first one that says Mr. Funman C.E.O., go in there and you'll be greeted to a chest behind his chair, inside it there is a book that says "FUNMANS WILL" read it and he will talk about his will and how his son was very dumb, but the most important aspect of his will is how he talks about an omega switch, Another room has a pig that if you press a button, you will put him out of his misery.
This was one of the first maps I played, and is honestly my favorite Minecraft map. It holds some sort of sentimental value to me, with it's classic Minecraft mechanics and it's old times, it can't be replaced. Even with all of these new features, this is the true meaning of a Minecraft map. Thank you, superpish.
