[GPG]

I downloaded Super Mario Bros 3 on my Wii, when I got to the doom ship in world 5, I died the first time, the ship then moved to the first map in world 5, when I went to the first map, the ship is not there, but when I go back to the 2nd map, it shows the ship being in map 1, I've gone back and forth many times and have tried everything I can think of to get to the ship. Is there something I am supposed to be doing that I'm not? or is this some kind of glitch in the game?
