Mario for Super Players

[Trudi]

I'm up to level 8-2 in Mario Deluxe for Super Players and i'm stuck. I get to a pipe that if I go down it takes me back to the start of 8-2. If I do not go down I am stuck as I cannot go any further because of a wall that I cannot get over. I cannot find any hidden bricks. How do I get through??

I don't remember the exact area, but you have to jump off a Parakoopa and discover a hidden block with a vine...

Yeah, I have the Super Mario All-Stars version, but it's the same. About halfway into the level, there's a pit with blocks and a red parakoopa flying up and down. jump on it and hit the block it was flying under, it will sprout a vine. climb the vine, and it will take you to the flagpole.

Where am I? Where''s my NES?
