Last update: 25 September 2019
At the beginning of this stage the playable characters are Bilbo and the confused goblin. Switch to any character and start smashing the objects in the area, including the barricade between you and the next part of the cave. After you get there, explore the area on the left and smash the small fence. You can now switch to Bilbo and walk through the passage here.
The passage will take you to the upper balcony. Walk over to the right here and use the stick, or the sword from the hobbit's inventory, to release the skeleton hanging on the chain. You can now return to the lower level and pick up the skull. You now need to go right, enter the aiming mode and throw the skull at the barricade above. Wait for the barricade to fall apart and approach the elements scattered around the place. Hold down the building key/button. For your efforts, you will be rewarded with three small platforms, which you can use to reach the ledge above and continue the exploration of the cave.
Switch to the confused goblin and use the fact that goblins can climb over the select walls. In this particular case, you need to climb the wall shown in the above screenshot. Go a bit ahead, jump down and stop. Smash the barricade right next to the chasm and start building again. The purpose of this action is to build a bridge for Bilbo to walk over . You can now go ahead.
Stop after you reach another big cave and start smashing the objects located on the right. One of them is a skeleton, thanks to which you will obtain another skull. Also in this case, you need to throw the skull and you need to aim it at the crate hanging on the left. After the crate falls to the ground and falls apart, start building again. You will build a Craft Plate. Interact with the plate and spend some of the supplies. What is required is 10 Rope, 15 Wood and 10 Iron.
As for the supplied named above, you could find all of them during the exploration of the cave, assuming that you have been destroying the objects meticulously. Wait for the minigame to start and try to handle it as well as possible. Approach the catapult and jump into it, as one of the characters. Switch to the other one, now, stand in the spot shown in the above screenshot and perform a regular attack, to activate the catapult. You can now enter the newly-unlocked cave, where you will meet the Gollum.
