World 5-B (New Super Mario Bros.)

World 5-B is the second bonus level of World 5, in New Super Mario Bros.. It can be unlocked by spending five Star Coins.

Layout
To begin this level, Mario needs to move while balancing himself on the slippery ice. Mario can get the first Star Coin by throwing a shell at it through a small spot. The second Star Coin can be obtained by pressing a P-Switch and by jumping over gaps to get to it. Soon, the player should see a Snailicorn. Mario should go past it to find the third Star Coin. To get a high spot on the flagpole, Mario should Wall Jump to a higher platform.

Secret Exit
To access the Secret Exit, the player must be Shell Mario. When Mario has to Wall Jump to a higher platform to get a good spot on the flagpole, he should continue to Wall Jump even higher, going above the screen. Mario should go to the left to find a pipe with blocks in front of it. Shell Mario must break the blocks to enter the pipe and to find the Red Flagpole. This opens a pipe that takes Mario to World 5-Castle.
