(I tried to find a topic on just the missions and help with them, so if I missed it please feel free to move this topic over to it)..

I took a little side jaunt to do a few missions before completing the story but am stuck on mission five.. I can see the star on my map, it appears to be just to the right of L'cie marker that gave me the mission, down a big tree trunk to a gully, but I cannot see it once I get down there.. The star disappears completely.. Once I climb back up it's there again.. It this some sort of secret monster that only comes out if it rains?

The guide says it's in the Tsumitran Basin, which I went all the way down, found another big bird and a couple of those big hounds/cat things but it wasn't the mark and it was a dead-end.. So now I'm really confused..

Any help would be appreciated..
