Rescue OOX-09/HL!

For those trying to hunt down:

[item=8704] from The Hinterlands (Personal stats: Killed some stalkers, some trolls, some owlbeasts (about 20 all told)... Then killed my first ooze at Skulk Rock, and it dropped)
[item=8623] from Tanaris (Personal stats: Went into Zul'Farrak like all other posters recommend, killed some twenty or thirty trolls and scarabs, and it dropped from one of the troll corpses)
[item=8705] from Feralas (Personal stats: As recommended by many other posters, Feral Scar Yetis - dropped on my first kill)

1. 
   
2. Only available if you have not already completed the quest.
3. 
   
4. Yes these still drop in Mists of Pandaria.
5. 
   
6. Yes it can drop off ANY mob in the respective zone, however [item=8705] has the highest drop rate from [npc=5292] IF you haven't already done the quest.
7. 
   
8. It WILL eventually drop - some days RNG is your best friend, other days you want to repeatedly punch a kitten (or other obscenely fluffy creature) just to illustrate how cruel the universe can be.
9. 
   
10. The command to check if you have completed ANY of the distress beacon quests is here (special thanks to MrsSushi for locating the updated version of this as of 5.0.3):
    
    

    /run local z={"Tanaris","Hinterlands","Feralas"}for k,v in pairs({{351,648},{485,836},{25475,25476}})do print(z[k])for i,q in pairs(v)do print(" #"..i,"\124Hquest:"..q.."\124h["..q.."]\124h" ,IsQuestFlaggedCompleted(q)and COMPLETE or INCOMPLETE)end end

    
    
    You will see lines of dialogue that look like this:
    

    Tanaris
    #1 [351] Complete
    #2 [648] Complete
    Hinterlands
    #1 [485] Complete
    #2 [836] Complete
    Feralas
    #1 [25475] Incomplete
    #2 [25476] Incomplete
    

    
    
11. 
    
    
12. After completing all three escorts, you can then acquire the quest An OOX of Your Own and get your [item=10398].
13. 
    

Happy hunting!

Followup of this quest is An OOX of Your Own, but available only after completing all 3 separate quests of finding distress beacons in corresponding zones:

1. 
   
2. Find OOX-17/TN! (Tanaris)
3. 
   
4. Find OOX-09/HL! (The Hinterlands, this quest chain)
5. 
   
6. Find OOX-22/FE! (Feralas)
7. 
   

As of 3.2 this and other Rescue OOX- quests are now 3 times easier! With less than a quarter of the mobs encountered and an escort route cut to the road just south of where you begin.

Only one wave of 3 mobs is encountered, not including anything that pats nearby.
