Hi, I'm completely and utterly stuck on Isla Cruces.

i just slid down a rope into a load of fish people (including cannon-arm-man), have completed all that, third crab pendant and all, both ways in, with the swinging obstacles, and with the dodging rock falls.

i've walked round to the left, down the slope near the river, and thats it. dead end.

where do i go next?

thanks very much.
