The Brain Tree is located in the upper middle right of the Haunted Woods. If you choose to except his challenge you will be asked to find out were and when a certain person died. The only way to find the answer to his question is by feeding the Esophagor twice. The Esophagor is located at the bottom left of the Haunted Woods. This greedy (whatever it is) has a huge appetite consisting mostly of Halloween food. The best way of getting this Halloween food is by looking on the shop wiz. If the wiz is too pricey you could help Edna in the Witch’s Cave ( located above the Esophagor) by finding the missing ingredients for her spell. Edna will reward you with anywhere from 200 to 2,000nps and a Halloween food. The more times you help Edna the higher your reward becomes. Once you feed the Esophagor once he will tell you when the person you have been looking for died. Feed him a second time and he will tell you were he died. After getting this information you will be able to answer the Brain Trees Questions. If answered correctly he will give you a handsome amount of nps and a rare battle dome item good for fighting with or worth bundle of nps.
Make sure you accept the brain tree’s quest before feeding the Esophagor. If not the Esophagor will only give you some sort of organic food not nearly worth the nps you spent on him. Also, if you decide to help Edna remember that the Brain Tree dose time you (normally 50 to 60 minutes) so you don’t have all day to fool around. Another tip is to write what the Esophagor tells you. This might take you an extra minute or two but it will save you in the long run because The Esophagor will only tell you the answer once and it would be a shame to feed him and then forget what he told you. Last, I would not spend more the 20,000 to 30,000 nps for the Brain Tree quest. Once I spend 15,000nps and was rewarded 8, 523nps and an attack fork which I sold for 20,000nps. But I also spent 25,234nps before and was only rewarded 1,000nps and a Garlic Shield only worth 500nps.
Yes, I think helping the Brain Tree is a good idea if you follow the direction in the second paragraph. Even if you dont like to or just dont battle it still could be a good idea because you can sell the battle items or give them to a neofriend if youre feeling like being super nice. Feeding the Esophagor with out needing its help, is a very bad idea unless you like wasting nps. Like I said before he normally only rewards you with organic food not worth that much anyway. Helping Edna is a half and half chance of it being good or bad. I normally help her if she doesnt want you to spend too much nps and then put the Halloween items in my Safety Deposit Box for a rainy day. My advice would say help her once every week to two weeks and just keep the reward or sell them. – Tabbycat_541
