New Super Mario Bros. 2 Cheats :
Same as Mario on the NES. Go to Mushroom World course 1, the place where the first star coin is. Stand on top of the stairs and wait for the noko noko. Go down to the second or third step and wait for the noko noko to reach you. Jump on it lightly (not hitting jump when you hit it) and then it should bounce off the wall and Mario will keep jumping on it, allowing you to get 3 crowns in a few minutes. Note - If you try this as Golden Mario, the Noko Noko will disappear after 25 hits.
