Pumpkin on one of the end obsidian pillars
"OH MY GOD NO DONT OH MY GOOOODDDDDD"
*Creates giant enderman that swallows the enderdragon, and gets pissed at you like an enderman would*
EDIT: Because of the handicapped singleplayercommands breaking the .jar I had computercraft in, I had to reinstall.
Computercraft requires ModLoaderMP for 1.1, and the ModLoaderMp 1.1 link is broken. Hopefully I can find that older version somewhere else.
