Brain Tree
What is the Brain Tree? The Brain Tree is a smart tree which has a huge brain on top of a mutant tree which exists in the Haunted Woods. This Brain tree only hungers for information from quests he gives daily to neopets players.

What does it ask for?
The Brain Tree will ask for the time and place of a person who died in what year or so. The only way in which you can find out is to do the Esohphagor Quest twice. Once for the time and once for the place. The Esophagor can also be found in the Haunted Woods next to the Brain Tree.

I saw on another site a list of Brain Tree answers.
No matter how much you try, they will never be right. Brain Tree answers are all randomized(changed daily), and the only way to unlock the actual correct answers is by doing the Esophagor Quest twice.The first item is always the cheap item ,then the second item is very expensive from my experience.like the esophagor could have the first item which costs 500np and then the second item which costs over 10k.
