I finally got him!!! I couldn't have done it without the help of Blooddsurge (who initially let me know the last two times he had spawned, so we were able to narrow it down), and to Phyra, who lent another pair of eyes to our search and provided more spawn times to go off of. He had been killed at 8:49 p.m. Friday night, then last night at 8:10 p.m., just 40 minutes before I got home. So, I checked the area after 6 hours (2:00 a.m. this morning) and he wasn't there, then again at 12 hours (8:00 a.m.), and he wasn't there, then again at 24 hours...and at 8:26 p.m., he popped up right in front of me as I was flying past his most northwestern spawn point. I freaked out. I'm surprised I managed to do it as smoothly as I did, but I quickly tagged him with an arcane shot, laid a frost trap at my feet, and pressed tame. I swear that tame bar took about 10 minutes to go down, the entire time I'm paranoid thinking someone would yoink it...but finally, he was mine! He spawned in brown which was my second favorite color, so I can say I'm very pleased. Green was my first choice, but brown (bronze/gold) was a very close second. Plus he has green details on the tail and mouth, so that's good enough.

So without further ado, meet Vulkoor!!! (Crap, just realized I didn't take any screenshots at all of his mob size, I was so nervous and excited!) You can see Blooddsurge's Terrorpene in one of the shots, and Phyra's Sambas in a couple others.
