Okay... I have but 2 questions... 1-You know the shiny squares on the..

You can muliply yourself by 2 and 3 until you need 4 squares.

In answer to question 2, he's talking about the cave with another "plant-thing", just outside of hyrule town, to the left of your house. He sells you a jar to collect water and spring water in, if I remember corectly.

I know that all the other answers to your 2nd question suck, but there is finally one that doesn't! MINE!!! Here you go! (It is NOT "that" hole. You need the Mole Mitts for that one) First of all, you need 200 rupees, bombs, and a good short term memory, because this is rather lengthy. When you are in Hyrule town, go to the place where there is a guard standing by an entrance to "somwhere" (that we know to be the Trilby Hihglands) and the post office above. Enter the Trilby Highlands. As soon as you enter, you will see one of those fox things. You can either kill it, or avoid it (I don't care which), but be sure to not let it hit you, of you will lose money. Go south. Here you will see a ladder. Go down it. You will enter a little cave, where you will see the shiny squares. Ignore them. Go East (right) to the wall, where you will see one section cracked. Use bombs ( if you don't have bombs, you're screwed) and you will enter another little cave, with one of those little shrub things. Reflect it's seeds back at it, and pay 200 rupees for a bottle. Fill it with water. Go to Mount Crenel's base, and Voila!!! Water the sprout, and you can proceed. If there is anythhing at all unclear, please feel free to yell at me, usind profane language (swears) if needed. Ah, but I have forgotten! I would suggest going to the "T" section on this site, and looking up "The Legend of Zelda: The Minish Cap" to find GREAT guides through the rest of the game. But you didn't hear it from me ;)
Ta-ta!
