New Super Mario Bros.: 5-4

This is a tricky automatic sidescroller. We have to deal with two kinds of special mushroom platforms. The yellow ones bring you down and the red ones raise you up when you step on them. They will return to their original position when you jump off. Making you life even more difficult are the Bullet Bills that fire off screen at your current position. If you're up for the challenge, try to collect the Red Coins. Immediately afterward, jump up high from the last mushroom to reach the first Star Coin and possibly the second if you're Mini Mario. If not, jump back down and quickly go around to the right, go up, and back left to get it. Use a shell if you need to. Just past there is the midpoint. You can get a 1-up with a shell here. Next are more red and yellow mushrooms. You'll find a red mushroom by itself at the end of that set of mushrooms. The third Star Coin is there. You can try to quickly get it or use a shell. After that are more red and yellow mushrooms to the flagpole. Be warned that the last two are yellow.
