Ok, I broke down the bird cage, jumped on the platforms, used the grappling hook on the red switch, went through the door and now I"M STUCK.
I can't use the grappling hook to go to the right ledge where I need to go. I can only swing to the one infront of me and that's basically nothing.... does anyone know what I'm talking about.... Help me please. i would appreciate some advise.

Sounds like you're just having trouble repositioning your swing. Once you've grappled, hold down the R button to stop your swing... while still holding R, you can change your direction while grappled ;)

Hey Thanks,
I got passed it anyway just by jumping. I'm off the island now, we'll see how I do in the Forbiden Forest...
