Hello I got three questions 1-how do I use or get on top of the sparkling..

This is for question 2. You need to get the second element and got to this place,get a new sword thing and the you can power it up and when it's full you can multiply your self. Hope it helps. Good luck.

For 1 Run into the sparking tree and surprize and for 3 you will get later in the game.

Whatever

This is for question 1. You need the Pegasus boots, and you charge them up, and run into the sparkling trees. They will smash apart, and become a minish portal!

I don't know how to use the sparkly trees
But
I do know what to do with the shiny floor tiles and where the item that lets small people move big things is although I havnt got it yet.
The shiny floor tiles you can use after you go to the bottom floor of hyrule castle and go through the shiny door. The game teaches you what to do from there.
The item is in the small hole in the fountain in hyrule town. You have to go into the mans house where you first heard of the item (but on my game he wont let you in as big)and put out the fire. Then you have to turn small and go into the house through the blue hole. Then you have to go up the fireplace and across the plank of wood and talk to the minish in the house (I havent done this yet so I don't lknow what they say) then go into the travellers house next to the minish house. Once your in leave the other side there is nothing for you to do there. Walk down the other side of his house and cross the small waterfall. Then go up and into the place with the cats in. Walk round them and down to the middle of the fence where there should be a bench with a rope underneath. Go down the rope to the fountain and around th fountain into the hole. The item shoud be in there(there might be other things in there to because I havent been in there).
