So I was flying around Winterspring and I ran into a rare Rhino and instinctively killed it hoping it had some sweet loot, but it just had a green.
Then I realized that Rhinos aren't supposed to exist before Northrend. So I checked out Petopia and learned that tons of new rares were added, some with unique skins, some just allowing you to get them earlier (like the Rhino) or in an easier way (like the Chromatic Corehound).
My question is this: do any of them drop any useful loot (special gear or vanity pets) besides a green or a tear or loyalty? It'd be nice to know which I should keep an eye out for and which I should just leave be.
Also, anybody got any of them? Enjoying them? I think the most frustrating part is still no more stable space. I have full stable space with all unique skinned pets from northrend/cata and a few others. I can't part with them!
