So I'm looking at the wiki for the quest and theirs a list ( which says the monsters but not a complete list of items )
 
In the quest castle 5 items are on display but not the others listed on the wiki , neither is their a reward "Grand prize"  no book on hints  like pirate quest or anything.
I have killed one of the monsters on the wiki but not in the display room and not gotten the items listed on the wiki , makes me think it is not added to its loot list 
 
Plus I can kill the Mythical Pink Unicorn 2-3 times a day with others also hunting it but yet camp Sasquash or Abomitable Snowman for days and only see them once.
 
Godzilla spawns almost right away and killed Kong 7 times in one day once..
 
I know we got to "hunt" them down and it should be a challenge but if they all had the same respawn  someone might actually complete it 
Items on display I have 4/5  but listed counting the mysterious ones I'm 4/9
 
Has the item list changed for it to the smaller 5 , or is it the display room is out of date  .   Them rooms help so much on the larger quests and gives us a base on how hard or long a quest might be.
 
Would love some input on it  thanks
