Within this 6 x 6 map there is (only things that matter for this challenge)
Mine Shaft (chests unchecked hope your lucky)
2 Sunken Ships (1 has treasure map)
The challenge is as follows
Hard Mode (3 lives, If multiplayer of group more then 2, 5 shared lives)
Build a Tower Homebase on starting island (atleast 20 blocks high)
Conquer the Water Temple
Additional goals can be added. But for now the idea is that you are to somehow manage to find where the 2 sheep are (hint: they are very very close) before 3 days pass. On top of securing a source of food so you don't die of hunger. The final goal of Conquering the Water Temple simply makes all the other general things a necessary step so there is no need to add them. (Find Diamond for enchantment table, Finding cows for leather etc)
Note: I did not add building Nether Portal because that is probably the easiest thing to do nowadays.
