Yellow Junkhopper

Followed the advice of going into Mechagon, just now on my second try a rare Yellow junkhopper!  Second pet was a Clanking scrapsorter without explode up but I captured the Yellow junkhopper.  Seemed the harder to get.

Took the advice of some of the posters here and tried resetting the dungeon and checking with a /tar Yellow Junkhopper macro each time.  The eighth time that I entered the dungeon I had a Yellow Junkhopper on the beach.  Got stupid and killed it by accident.  Came back in an hour and started entering the dungeon, running the macro, then exiting and resetting the dungeon again.  Got another Yellow Junkhopper on the beach on the ninth try, and captured it.

Just got an uncommon one directly north of the horde FP on the beach it was the primary pet. Just flew around moonfiring all the fleeting frogs (battle and non battle ones) on a path from horde beach across to the lake then down the west coast. Think it took four passes to spawn :D

I got mine right after maintenance over on the west coast of the island by the little gnome.  I had tried going into the Mechagon dungeon and resetting several times over the course of days, but never saw one.  This was the first and only one I have ever seen.

This was by far the worst Mechagon pet to catch. I finally had one spawn for me on the south-west coast of the main island, opposite the western spray islands after around 2 hours of waiting in the same spot. Prior to this, I killed every critter, and every fleeting frog pet that spawned in the area. 

This is nothing more than an arduous waiting game.

Got tired of resets so went in and just kept killing the non-battle beach Fleeting Frog until the Yellow Junkhopper appeared.  First time there was a rare Experimental Roach add and couldn't resist so had to repeat until a second Junkhopper showed up.

I am so done with that.

I got this and the Roach from resetting the Mechagon dungeon, the roach spawned near the path where you zone in (near the beach) the Junkhopper just around to the left of it.

Without a doubt the BEST tip I've ever seen on this site. I took the advice I found here and went into the Mechagon instance. It only took 12 resets until I had my Yellow Junkhopper, two achievements, and a new Kelpfin pet!

Got a rare at 47,2 31,2 first kill jumper and after a time the yellow appear in the place in the plump. first kill Jumper in the plump afterwards respawn.

Got one on west coast side, this one was uncommon only though. 

I have never been able to find this on the regular Mechagon island. I went into the raid and it was on the Alliance beach my first time. Thank you for the comments! I would have NEVER looked in there!

I was able to get it AND the dusky snooter as well as two other pets inside Mechagon, just going in and resetting it when nothing there.

I became very tired of searching the island for this pet, haphazardly killing every fleeting frog I encountered, so I went into the instance. After about 10 resets, I found this little guy on the alliance beach and he was mine. I suggest following the previous poster's remarks about getting this pet in Mech. It was a primary.

Four other addition locations of Fleeting Frog (the regular spawn) are on beach next to the fisherman gnome west. Alliance landing point beach. Down SE near Scrapclaw and the Toxic horrors. Due east of Western Spray/Freza on the empty beach. Was clearing out FF myself, till i saw one Yellow Junkhopper only getting killed accidently by random player YIKES. Got the tip to check inside Operation Mechagon, so I went in, and my macro picked up a spawn on alliance beach. So perhaps worth checking.

Saw it also as a secondary in Machagon dungeon.

If you're looking for the pet solo in the dungeon, my luck was as follows: in almost 50 resets I saw 1 Yellow Junkhopper as primary (on Alliance beach; don't go to Horde beach or else you'll be vaporized) and 1 as secondary to a Duskytooth Snooter (next to the trogg area). I also got the 3 wild dungeon pets obtainable solo (as secondaries). The chances to see a pet next to town are low, so keep retrying.

Pretty poor spawn rate, and no real reason for it to be such a rare spawn, spent over a week now, butchering hundreds of frogs but yet to see it spawn.

What a slog. Found mine near 46.5, 30.2. That's where I was standing, it was in the water and the first line pet. I'd been spending some time each day checking pets and trying Fleeting Frogs and nuking every pet and critter in sight. Good luck!

I've been slaughtering so many poor Fleeting Frogs, and still no Yellow Junkhopper for me. I've seen far more FFs in the a.m. hours than in the evening -- wondering if anyone else has noticed this?

Next morning -- Definitely far more fleeting frogs now (6:30-8:30 a.m.) than there were last night. Still curious to know if others are having the same experience. (Still no junkhopper, though...)

Found mine at 48, 38; chilling at the southern tip of the pond in the Fleeting Forest.
