Crusty the crab is the only rare in this zone with a large patrol route. He is also the only neutral rare in this zone, and he's tamable by hunters. He even has his own post on this blog here: Crusty.
The rest of the rares in this zone have multiple spawn points in different general areas, but they do not move between these points once spawned in.
Hissperak the Basilisk will also be tamable in MoP, and his colors will be changing slightly to purple/pinkish accents instead of blue. I believe he will also have a unique skin. =)
