Well dang, looks like I'm getting this error now. I've been able to actually load my character on the WoW Armory using the warcraftpets link too. >< Any fix for this currently? Thank you.

I had this glitch as well. I tried leaving the area, removing Uuna and bringing her back, etc. However, the snail toy DID work. It killed him and once he spawned again (almost immediately), Uuna was able to do her magic.

Celestial Dragon

This beautiful little guy is hands down one of the best pets to have in your group of three. Not only does he look dazzling, he also has an extremely strong heal once you use his Moonfire. Once this guy is on the playing field, opponent pets start shaking in their tiny booties.
