How do I get the vulture's meat?

Hint 1 of 7:

The first thing that you need to figure out is how to get close to the
vulture.

Hint 2 of 7:

There's a switch on the wall that will make a box just underneath the
vulture pop up.

Hint 3 of 7:

Try sending both goblins up, and you'll notice that one stays up near the
vulture longer than the other.

Hint 4 of 7:

You want W to press the switch while F stands on the box.
