I can only think of a few places in Maridia where you would be stuck. From the broken tube, go up to the middle door (getting the missle if you want) Go up to the next screen. In the flat area, charge your shinespark. Jump up to the platform on the right, and shinespark diagonally right. You land at a door on the upper right. From there, go down (there are some nice items up, but nothing necessary) you'll come to a large room. Use a power bomb to go down, and then wall jump up to the door above you. use your beam and speed dash to get through this room, and you'll meet the mini boss. After you beat him. speed dash across the sand in the next room, charging a shine spark before you enter the next room. shinespark diagonally up when you enter the room, and go right. Get through the next room (the grapping hook isn't necessary btw), and go into the super missle door in the bottom right. Fall through the floor, and you will confront draygon/space jump. If you want the morphball jump, back track to the room you speed dashed over the quicksand. Do so, but this time, stop at the very end of the quicksand. Collect the energy tank if you want, and fall through the sand. Exit to the left, and go to the bottom right of the next room. Shoot out the floor and fall through the first quicksand area. go to the right, and shoot out the grappling beam block in the middle of the room. It will disappear, and you can go up then down. Equip power bombs before going into the next room, and use on immediately to let the monster eat through all of the sand to get the morphball jump. Back track all the way to the left to exit maridia. (the plasma beam is somewhat on the way out of maridia, power bomb the room just to the right of the sand/mini draygon area. you'll be 'warped' to a area higher up in the level. Use your space jump/wall jump to get into the awkwardly placed room to the lower rightish.
