World 1-5 (NSMB)
It has been requested that this article be rewritten.
World 1-5 is a level of New Super Mario Bros. full of mushroom platforms.
Overview
Mario will use the some pink, bouncy mushroom platforms early in the level to grab a Star Coin. After this part, many Koopas will appear, but it is very hard to hit a Koopa twice. The next part of the level involves lots of platforms, connected by a pulley. If the player stays on one too long, it will break. A green pipe is above a pink bouncy platform-- One must hold A or B to do a super jump that leads to the pipe. It leads Mario/Luigi to the third Star Coin. More bouncy platforms and a Red Coin Ring appear before the finish. For the Red Coin Ring, the player needs good jump control; the only dangers are falling off or being nailed by the (probably deliberately placed) Goomba that wanders erratically down the platforms.
