Run left until you see a large spider hugging a tree. It will attack, stand well out of range until it stops. Once it has, move close to it, until one of the legs moves towards you. Quickly move out of the way and it will strike the ground.
Run back to the left and you will find a bear trap. Jump over this and push it back towards the spider. As before encourage the spider to attack you, butplace the trap exactly where the spider strikes the ground. This will remove a leg. Repeat this three times and the spider will retreat. Continue right.
After a short while, you will stop moving, having been caught in the spidersweb! The spider will come and tie you up before exiting to the left. Once it is gone wiggle away until you drop down to the floor below. Hop across to the right, jump across the gap and continue up the hill.
