(shhhhhhhhhhhhhhh it a secret)
Follow the crab Talk to Herbert Lift the Cage Pick up Hook and Rope and G plan pick the Hook and put on to the rope
After you get out of the cage, look for the anchor in the cave. then by the cage lift there are wooden boards. On one of them is a rope. Tie it to the anchor then go to the area you first arrived in. Click on the cliff then use the "grapple hook" and you'll be out of the forest.
You get the rope from the penguin at the dock, then you take it G's invention to the left of the cage and drop it on the top, it will now be connected to the cage. Pull the lever on the right side of the lifting device (the box, G's invention, whatever you want to call it) by clicking on it. The device will break, so use the tool on your phone to open the front of the box. Click on it to move in closer, and put the gears back it. This will take some testing to get them all in the right place. When you get it the device will be fixed, so click on the lever again. The cage should now lift up.
