Don't Dig Down! (A Minecraft Adventure Map)

First of all, this is my first Adventure map so don't be hattin' on me.

Inspired by Skyblock and the 404 challenge (sorta) I have created this medium, difficult adventure map. Basicaly your are on a giant floating island and you need to find the long lost cave... and retrieve the Wool... yep.

Rules:
-No breaking Iron doors
-No diggy-diggy until you find the dungeon
-No mods.
-No see through texturepacks(wire craft, ect.)
-No dying the pink wool! (any other wool is fine)

Challenges:
-Build not a house, but a mansion!
-Find the Godly Pink Wool!
-Find the cave and plunder its goods!
-Create a wheat farm
-Survive.

Post pictures of your mansion and other things.
Hope you enjoy, oh and if you download the map and your in creative mod please tell me that and tell me a way to fix it... thank you.
