This is really bugging me.
I joined a group for Twilight Arbor explorable last night, and one of the party members was a ranger. But, they had a Tropical Bird pet? It was attacking mobs, so it had to have been a pet. I can’t find anything anywhere about them being tameable, and I am kicking myself for not having taken a screenshot. I asked the person about it (I can’t remember their name, another blunder on my part,) but they didn’t answer.
The instant I saw Tropical Birds in Lion’s Arch I knew I’d kill to have one as a pet. Any ideas? Gah.
