Hopling

Sammy-Joe's guide is perfect.

Thank you!

ETA: Just wanted to mention that the targetting system can lead you astray. Often the Golden Hopling was a level above or below where you were.

Also, I changed the colour of the tagret a couple of times to make him stand out more. :)

so just got this little dude, and was a bit shocked as to how easy he really is to get.

did the run with a guild mate, brought the tea in the beggining, cleared all, then shift + V to see the name plates, ran and got all 30 of them and get the achive, and so did my guildie, so it seems if u are in the group with someone who dose it, you will get him too. a nice qucik way if you and some guildies are looking for him rather than one by one.

happy hunting.

here is my suggestion: 

Got two level 90 hunters(including myself) and a level 90 warrior from the guild and ran this on normal mode. While they ran around and cleared I followed behind them and got the golden hoplings with the macro (which helped so much!). Because we did this as we cleared, I went through 8 bottles of the drink. But it was really easy to clear!

It may also help if you have the glyph for your druid that allows you to track critters along with humanoids while in cat form. However, sometimes if there are too many hozen left it can be hard to pick out the Golden Hopling dots from the Hozen. Additionally, they will only appear as dots on the minimap unless you have drank the tea. Hope this helps!

That macro was extremely handy. Note that it doesnt count how many you have found on ur achv bar, so its hard to gage how many you have gotten unless u count them.

In terms of the pet itself, it's pretty decent - humanoids are one of the rarer families, but the Hopling does them proud. Some strong offensive abilities, access to 3 different types, a pseudo-stun, a snare, and the awesome humanoid trait which effectively gives it a heal each turn (hint: works well with Backflip and Lash). Actually, the moveset is pretty darn awesome in that your options for the second and third abilities are all different.

In regards to the golden hopling that seems to be un-obtainable.... 

I had the same problem. It actually spawns at the top of the stairs by the door. If you happen to get this spawn, remove your buff and re-apply while speed clicking at its actual spawn point. It took me a few times but I got it. Seems it is just bugged and will fall through the floor. Thank goodness the hoplings arent always in the same place.

There's one spot where a Hopling can spawn and be unreachable. My friend and I spent several minutes trying to find a way to get to it; he even tried using the priest grip to pull it closer. No go, so will have to try again on another run. Here's a screenshot to show you what I mean:

(Don't mind my size -- tried using the World Enlarger, in hopes that a smaller figure will be able to get into the space. That didn't help either. /sadface)

This helped me out finding my 30th hopling. After 3 full searches through the dungeon after we had cleared it, I whipped the following macro thing out and found the last one cleverly hiding.

/tar Golden Hopling

Just regarding Ling Ling's favourite tea. You can only carry 5 of them at a time and they last 5 minutes each.

Best to do this after you clear Stormstout Brewery. After the group leaves, go all the way back to the begining of the zone and look for a ghost npc named Auntie Stormstout and buy a few of Ling-Ting's Favorite Tea.  Next, drink one. Then use shift-V to turn on name plates, search every corners and nook and click on the little golden bunnies. There are 30 total in the entire dungeon.  Keep an eye on the buff, if the tea wears off you can't see the bunny so drink another.
