Snarler is difficult to find, because he moves around in two different locations. One is near the Lariss Pavilion, and the other location is to the right of it (in between the Lariss Pavilion & The Lower Wilds). That is where I found my Snarler, while some people have found it near the Lariss Pavilion. Just remember not to give up, he is CLOAKED, so you will not be able to spot him unless you use flare, or happen to bump into him. Don't give up finding him, just grind around there if you're really bored.

Happy hunting =) took me 2 days to find him, but well worth it.
