Looking for Behemoth or Odin

Hey all, Zozon here. I've been hanging out in Coerthas hoping to run into Behemoth for a while now with no luck. If anybody sees him out there I'd really appreciate it if you'd let me know. I'd even be happy to throw a few hundred gil your way if I'm online and you're the first one to tell me about it (wouldn't really apply though if I was out fishing in Coerthas watching for the fate like usual).

If anyone wants to post a time they last saw him so I can try to be around when he might pop, that'd be really helpful too. Of course, Odin sightings are great also. I'm sure I'm not the only one out there who'd like to kill these guys and wear them as hats (yeah, I know the gear is bla, so bla bla - I don't really care, I just like helmets with horns. Or... antennae? whatever Odin has) so, help a Lala out. -Thanks in advance

There's dedicated linkshells to reporting these instances popping up, or, join a larger free company.
Word spreads fast since it takes A LOT of people to kill them.
