LOST: CYOA 5 (doll)

You climb up to get the doll. It's really high up, and you take a break to catch your breath. The view is spectacular... and is that a symbol marked in the ground with red sand? There, just beyond the plane in the tree?

Forget the doll -- you'll get it later. Do you head for the strange symbol? Or do you forget the doll and the symbol and continue searching for a coconut?
