I really need help! I'm on the thing with the monkeys I have three of the..

What you need is the boomerang. If you have that then you will be able to get the chest down by getting out your boomerang and aiming it at the white string holding the chest up. To get the chest behind the doors look at the ground in front of the doors by the fans, you should see a pattern like a zigzag. If you aim your boomerang at each fan so that it follows the path the gate will open. Good luck!!!

The monkeys lead you half of the way, just follow them. You need the item known as the Gale Boomerang to get certain chest which can be taken frow the monkey that destroyed the bridge. Get one more monkey and you can get across. You will need to solve problems to get more monkeys.

P.S. They stop leading you after you beta the mini-boss.

First of all you have to get the gale boomerang by beating ook you can
Use it to hit the white string holding up the chest

Second I think you mean the chest with the big key in it if I'm right you just use the gale boomerang th hit all the prepellers but you have to do it in order first far left then far right then near left then near right
Hope I helped

ps if the are any other thing bihind gate just do the same thing but it doesent matter in what order just for the big boss key
