Man this game has so many memories and i beat the game 20 times!!!Okay if you got this game i will tell you about the 2 whistles to beat the game quicker,first go to the 3rd level at the beginning and keep walking and once you find a white block,jump on it and hold down until you go through the white block,then run to the end and you should be talking to toad and you have claimed the 1st whistle!!! The second whistle is at the castle on world 1,first get the feather and keep going until you see the brown door.Don't go into that door or you will have to start it over again.Okay get speed and fly,then keep flying over the block at the top and you should then start moving over the blocks and walk all the way until you can't move any longer(by the way you can't see yourself because your on the blocks all the way in the sky).Keep moving right until you can't go any further and press up so you can into the secret room and get the second whistle!!!You can now use them and go to any place in the game you want to go to!! Hope this helps.
