Creature of Fenkenstrain

Walkthrough
After you've started the quest, go northeast to Fenkenstrain's Castle. Talk to Dr. Fenkenstrain to interview for the job. When you describe yourself in one word, answer "braindead". Tell him that your best skill is gravedigging. You now need to get body parts. Here is how to get each part:

Head -

Wear your amulet of ghostspeak and talk to the headless Gardener Ghost. Ask him about his head and his name (write down the name). Then ask him to help you find his head. He will follow you. Take him into the Haunted Woods (other players can't see him, and you can't teleport or go to Canifs or Mort Myre). Read each tombstone until you find the one with his name on it. Talk to him, then dig to get the head.

Brain -

Go to the bar in Canifs. Talk to the bartender and buy a pickled brain for 50 coins. Use it on the empty head.

Arms, legs, and torso -

Upstairs in Fenkenstrain's Castle, read all of the books in both bookcases to get two triangles. Use them on each other to get a star. Go outside. East of his castle, you should find some tombstones. Search the big ones and use the star on the one with the indent on it, then push it. Kill a level 51 Experiment to get a key. Take the bones if you haven't done Ghosts Ahoy. Then find a door, open it, go up the ladder, and dig at the three tombstones.

Give the body parts to Fenkenstrain. He will ask you for a needle and five spools of thread. You can buy these items in Canifs. He will sew the body together.

You now need to fix the lightningrod so that the castle will get struck by lightning, bringing the monster to life. Ask the Gardener Ghost for the key to the shed. Go inside and take the brush. Then go outside and take three canes. Use them on the brush to attach them with bronze wire. This will extend it, making it suitable for chimney sweeping. Go upstairs and use it on both fireplaces to get a mould.
