The wishlist is an 'extra' quest that is given by the Odd Old Man. This does not need to be completed to wear the Quest Cape. The Skeletal Horror fight at the end, however, unlocks a new song which is required for the Completionist Cape
The wishlist on the shack is also listed in the quest log for Fur 'n' Seek. As each bone is obtained, the following is added after its listing: (I have an unprepared one with me.) If item is banked, the sentence changes to (I have an unprepared one in my bank.). All acquired dragon tail-bones are also listed. As each bone is prepared with vinegar and fire, the word 'unprepared' is removed. As each bone is given to the Odd Old Man, that quest log entry is removed.
For the dragon tail-bones, an additional line is added below the entry: Tail-bone of 9 different members of the dragon family. I have an unprepared (name of dragon) tail-bone with me. After each prepared tail-bone is given to the Odd Old Man, the entry changes to (Name of dragon) tail-bone with a line through the name. The number decreases for each bone given to the Odd Old Man.
Note: To check which dragon tail-bones have yet to be handed in, check the Fur 'n' Seek quest journal.
Found in Brimhaven Dungeon, in the northern courtyard of Ghorrock (during and after The Temple at Senntisten), and in Kuradal's Dungeon (requires a steel dragon assignment from Kuradal).
Green dragons are found in several places in the Wilderness and in the Chaos Tunnels. Brutal green dragons are found on the lower section of the Ancient Cavern.
Found at the end of the Fremennik Slayer Dungeon. If you're completing the wishlist without level 78 Slayer, be sure to take some boost to fulfill the Slayer requirement.

After you have obtained and polished all the bones (using the method All the bones ready for the Odd Old Manfrom Rag and Bone Man), the old man will summon a Skeletal horror, a level 130 monster, to the platform North-East of him.

If you have not, you must do the other wish list before you can kill it. )
The monster loses bones as you battle it. You must quickly collect these bones and bury them to weaken the monster. If you don't collect them, the fallen bones crawl back to the monster and restore its life. Use the Protect from Magic prayer and you should have no trouble with it.
After defeating the monster, you will have finished the miniquest, and can talk to the Odd Old Man to receive your reward.
After the miniquest, the Skeletal horror can be fought again once every week after the last battle, giving 1,250 Slayer Experience, and 1,000 Prayer Experience after each fight.
