If you dont know yet then this information can be useful. there is a new character when you have beaten the game once.
This character is the dark wizards brother he has even stats to begin with and he is really tough also you know impa's palace?
Well you now that weird thing halfway through it that keeps poping up and down well chose a spot and make sure you have alot of bombs or grenades.
The best bet of hitting him is when he goes down the moment he goes down throw a grenade or bomb and hopefull he pops back up.
Now when you hit him three times with a grenade or two times with a bomb he will die.
Now go to the top of the room and you will see an opened passage (this open passage is in the centre top wall not the one with the blue arrow on the right corner), go up the passage and you will notice a blue box, just keep on attacking it until it bursts open and you will receive a yogurt ring.
Now if you do the same thing on the advanced part of the game you will receive a yogurt summon level 1.
