There is something else i can't beat, the last castle in world 3. How the hell do you kill that mario eating plant? I don't understand it.

can you tell me how to get to the key

u know the monkeys and the trees in the beginning? U hop on those until there is a stone
walkway and an arrow go through there and you will find the key

i beat the last castle on world three all you have to do is throw your egg aganst the
other wall the wall that dis int have the big monster.

I'm on world 6 the first castle thinger.

And i'm at the part where you have to travelt through the dark and i cant seem to find my
way.

i couldn't find it either
you hop on the trees until you get to the stone walkway and once you get the flower fall
and go to the left and hop on the thingie and there is a key

when you start the level jump on the first tree on the corner of the hill then jump on
the other trees then walk right for awhile then when you are in the cave walk right
until you get to the mushroom then jump and you have the key!
