I spawned in an island world -to my delight- in the first 1.8 game. I promptly went out swimming in search of a cool island.
And... no trees... no animals... just islands with grass. I managed to find a mine shaft in the bottom of the ocean, got some wood and made a boat.
Searched for a while longer (until I reached x:906 y:-7034) and finally found an island I want to settle on. Along the way I found an island full of pigs, so that long with the bread from the mine shaft should keep me okay for a while.
The problem is, still no wool. After searching 50-75 islands, only ONE had trees or animals. And that was only pigs. I have saps, so I should do okay on wood. And I should be able to make bread, I think. But if I lose focus and get killed by something than I'll go back to spawn. And I'd hate that, so much so I am willing to cheat a little to get a bed. But how would I do that?
tl:dr? Need bed, no sheep, tell me how to cheat.
