This was a glitch that I found on accident while trying to do a speedrun of Minish Cap on a seperate file. What you do is at the boss of the third dungeon(I don't remember his name), when a hand is about to pound the ground, kill the other one. It should come back and, if you did it right, try to grab you and when he is about to pound you to the ground, start mashing buttons. If you did it at the right time, the other hand will pount the ground at the same time as the hand grabbing you. If so, the one grabbing you will let go and you will just be a crying head floating in mid-air. The good thing about this, you are invinceble. The bad thing, you have to shut your game off and battle him again.

Go to your grampas house go to the left of it and dig till you find a certain spot there will be a red rupee and if you go inside you will come back out dig and it will be there again

Good luck

This is useful as it does not require the shovel, and can be accessed from earlier stages of the game(Mt. Crenel and beyond). In the room where you have the switch which you throw a bomb at it, which creates a bridge going across.
In the room, there are three pots at the top behind three stone blocks. They usually have 5 bombs inside them. But, towards the end, you have two pots next to each other. The left one contains something random, but the right one ALWAYS has a red rupee. The exit is only a short walk south, then if you come back and hit the pot, the red rupee is still there. Keep going in and out until you max out your wallet.
This is very useful because it allows you to buy the boomerang earlier without the risk of running out of money for the wake-up mushroom.

In town the one selling picolite will get 3 other sorts by going inside the large barrel
In the minish village in the woods.
There will be 2 picory, 1 saying they make humans happy and 1 asking for something.
Bring the item to him and wait some time.
Next time he will have a new flower wich will be sold by beetle in town.
Repeat this 3 times and he is finished.
The old+new ones are:

1. Item finder (old)(blue)
2. Mysterious shell finder (old)(green)
3. Heart finder(old)(red)
4. Faiy finder(third)(orange)
5. Rupee finder(second)(yellow)
6. Kinstone finder(first)(white)

Its best if you already learned the super spin longer and keep the spin around a large field of grass.

Take a Semi-Big Puddle (not like a lake or anything). Use the mole mitts to dig around the puddle until what was a big puddle is now really tiny. A fun cheat...

To get the Spin Attack upgrade fuse Kin Stones with the trainer in Mt. Crenel.

Get a shovel and dig to the left in front of the door of your house. 20 rupees will pop out. Go inside and come back out the the rupees are there again! Do this as many times needed. Thanks for listening.

When you get into town, there are 4 rugs. A rug with a guy selling vegetables, the other guy selling fruits, the other rug is empty and the other rug has dust on it. Use the gust jar to blow all the wind away. Come back in 30 minutes and the guy (Beedle from Zelda :Wind Waker) will be there selling magic fairies. The more important things you do, like getting a medal from a dungeon. Something like that, you know important things. ANYway you'll get more faries. I believe you get a rupee finding one, a heart finding one, a kindstone piece finding one,M. Shell finding one, and I think thats it. Thanks for listening.

MAGICAL BOOMERANG: ) you have to fuse all 4 kinstones with those guys dressed in wierd clothes.(theyre standing on stumps ) after that a cave wil appear in the north hyrule field. Thats where the magical boomerang is.

LIGHT ARROWS:) okay first you have to fuse a kinstone with a guy in hyrule town (sorry I forgot which house but all I know is that his clothes look different from all the rest of the other people) anyway, after you fuse, a portal will appear in hyrule field. Go there and use the gust jar on the flying ghost. The guy will give you nothing now, but later you will get the light arrows.

REMOTE BOMBS:) fuse a kinstone with the elder in the minish village. Then the bomb guy (who origionally gave you bombs) will have remote bombs. Go there and switch your bombs for remote bombs. You can switch anytime you want.

MIRROR SHIELD:) get all 6 gorons to break the wall inside of the goron cave. You have to do this by fusing 6 kinstones with peoples. You have to fuse w/ eenie and the 5 mysterious walls that are underground. After all 6 gorons are done breaking the walls, get the bottle thats in there, and fuse a kinstone w/ the 6th goron. This will awaken the biggoron. If he tells you that you have to do some "major feat" this means that you have to beat the game. If you have beaten the game, he'll want to eat your shield and later you wil get the miror shield.
