Neopets Brain Tree Answers!?
Unfortunately the brain tree quest is designed so it is reliant on the esophagor quest. the only way to get the answer is to feed him, because the answer changes each time and the answer is generated specifically for you when you do the quest, so no one else will be able to give you the answer. You can only try the brain tree quest once a day, but when you try it give the esophagor quest a go, sometimes he asks for really cheap items.
