Talk to Brimstail about the creature that happens to be his new pet, Izzie. Ask about his research and then begin the quest. Walk through the tunnel and inspect parts of the machine. Also, inspect the Singing bowl which is on an unreachable pillar, then return to Brimstail and tell him you have looked in the other room. He now asks you to speak with Hazelmere.
Talking with Hazelmere
Hazelmere is located on the island of Jungle spiders east of Yanille. Use the Watchtower teleport, Fairy Ring code CLS, or ardougne cloak to speed up travel. Talk to Hazelmere and eventually he will cast a spell of telepathy so you only need to think what you want to say.
Upon completing the conversation and neat cut-scene, you will be given a Violet pentagon.
Return to Brimstail in the cave in Tree Gnome Stronghold and tell him what Hazelmere told you. You will now see a mysterious figure destroy the machine. After that cut-scene, talk to Brimstail again. He wants you to inspect the machine and find out what needs to be repaired.
You'll need to make some glue to repair the machine. Talk to Brimstail who will eventually tell you to get some tree sap. Go out of the cave and find a regular Tree that has a point at the top. There is one just outside the cave. Upon finding one, use your Knife on it and you will now have a Bucket of sap.
Now use your Mud rune on the Pestle and mortar to get Ground mud runes. Add the Ground mud runes to the Bucket of sap to make Magic glue. Head back and "Repair Oaknock's Machine".
Unlocking the machine
Upon repairing the machine, it will still be locked from use and it's your job to unlock it. First, talk to Brimstail for more disks, then try to unlock the machine. In doing so, you will be displayed a number (different for everyone). To solve the puzzle, you need to find the shape and color associated with that number. Each shape and color is given a numerical value. You need to multiply the number of sides the shape has with the number code of the color. Below lists the values for the shapes and colors.
- Circle = 1
- Triangle = 3
- Square = 4
- Pentagon = 5
- Red = 1
- Orange = 2
- Yellow = 3
- Green = 4
- Blue = 5
- Indigo = 6
- Violet = 7
You need to use the Exchanger next to the machine to give you a shape that equals the value you need. Click a disk then click the slot to place it into the machine. Now click the right-arrow button to exchange it. Clicking the right-arrow again will give you another combination of those values. Upon displaying the exchange, you can accept it to get the new disks or decline it to return the disks you put into the machine. Continue this process until you got the colored disk you need. Now you can use that colored disk with the machine to unlock the front panel. Insert the disk into the slot, and then click the green box.
Three more numbers
If at any time you don't have enough disks after unlocking the machine, speak to Brimstail to get more.
Now that you've unlocked the front panel of the machine, you need to do it again for three more numbers. The first slot must be 1 disk, the second slot must be 2 disks, and the third slot must be 3 disks. After a bit of thinking and exchanging, you'll have your 3 combinations. Insert them into the machine and then accept the transaction to unlock the machine.
A cut-scene afterwards will reveal that Brimstail's pet Izzie is an Evil creature.
Eyes of Glouphrie
Talk to Brimstail and find out that he thinks these creatures are actually spies for Glouphrie. You need to find all six and kill them. Don't worry as they only have 1 hitpoint each. Find them in the following locations around Tree Gnome Stronghold:
- Brimstail's cave
- Near the spirit tree
- At the entrance of the stronghold
- Next to King Narnode Shareen
- By the Gnome glider atop the tree
- Near the Tortoises north of the swamp
