Smokey the monster in the cave?

Did anyone else notice this?
If you listen carefully when Locke first enters the cave, before he finds the toy truck, you can actually hear the monster noise, the same sound the monster made when Eko and Charlie were out searching for the drug plane.
Listen very carefull, crank the volume, you can hear the noise it makes, we watched it ten times and heard it every time. Makes you think, maybe the monster takes on the form of a polar bear, or it resides in the cave with the polar bear?

nice catch...

Seems plausible. Maybe that's how the bears escaped from their cage?

Must say i'm really liking this theory. I haven't had a chance to rewatch it at all, but i swear i heard the monster noise too. Not sure if it takes on the shape of a bear or whatever...but i think its very plausible something along those lines could be taking place here. I'll have to watch this very closely...
