The Final Tears

Use little Midna and jump across the tree trunks in the water. Cross through the branches and go towards the top. There is going to be a swinging log on your path so you may want to avoid that. At the entrance of the cave down on the ground, two more insects are waiting for you but they think they are sneaky.

Activate wolf senses to locate the insects that are underground. Dig over to them and eliminate them, collecting the tears. Make your way into the cave for some fun filled shadow creature fighting. Beat them the same way as previously. If you remember where you found the monkey earlier, head down that same path and guess what? Insects! Defeat the final two and you will have acquired all the tears.

After collecting all the tears, original form Link is back in his own world. Make your way through the path and you will see that somehow the cave has been locked. Take the path you took earlier to find the lantern man, chat him up again and this time he will present to you a small key. The Oil Bottle can be purchased if you have 100 rupees with you. Take the key and head back to unlock the gate. Proceed through the cave and into the swamp.
