The worm that you have lost will reappear in Moltara.
The answers are randomly generated and different for each user. The only way to get the answer to the questions that the Brain Tree asks is to do the Esophoger Quest twice and he will give your specific answer.
My trick is if you find a newbie that has brain stew trade with them it'll probably work.
you can find worms in moltaro.not from random events.
Buy it, Money Tree, Trading Post, and Auctions.
It is right were the steps are to go to the caves. Keep refreshing and then you will find it.
you should be able to get them in the first day.
It's random when refreshing the page. A real pain.
If you are talking about the worms in Moltara, you can only retrieve them if you have an Empty Lantern in your inventory. If you don't have it, then when you click on a worm, it should say, "What a cute looking worm. Too bad you have no where to put it." I think. If you collect all 10 worms, you can go into the Cave behind the Magma Pool.
They're in the two main Moltara maps. You have to keep checking back every five or ten minutes or so as some are rare and take longer to appear. Or if you meant a different kind of worm, feeding your pets apples can make a worm appear in your inventory.
The worm colors are Blue, Yellow, Red, Orange, Purple, White, Pink, Green , Rainbow, and Black.
You can search for items using the search box located on the left hand side of the page (or bottom depending on your page) this will give you the information about the item. From there you can try to restock it or buy it on the shop wizard.
