World 3-8 (Super Mario Bros. 3)
World 3-8 is the eight normal and tenth overall level of Water Land in Super Mario Bros. 3 and its remakes. This level is accessible after 3-6 is completed, but can only be accessed if the drawbridge between the two levels is down. If the drawbridge is up, the player can complete World 3-7 and then have access to World 3-8. Chronologically, it is played after the second World 3- is completed.
This level has a similar gameplay design to World 3-3, as Boss Bass returns from that level and the tides change rapidly, raising or lowering any platform Mario is standing on. Boss Bass also always returns shortly after being defeated. This level has three Beanstalks as well to help Mario avoid Boss Bass's attacks. This level begins with Mario on a platform and Boss Bass immediately swimming below. As the tide lowers, Mario must jump on the elevated part of the platform. Next is a small gap to a lower platform that Mario can jump over entirely to reach the next platform. This platform has a Brick Block on either side with a green Koopa Troopa walking in between. There is also a Jump Block above that produces either a Super Mushroom or a Fire Flower. If the Brick Block on the left is hit with the Koopa Troopa's shell or a tail attack from Raccoon Mario, a Beanstalk appears and grows until it hits a Wood Block above. Next, is a small platform and then a raised one. The raised platform has two Ice Blocks stacked below a Brick Block. This Brick Block produces ten coins if hit ten times. To the right of this platform is a series of lower platforms. One of them has a single Brick Block on the ground which produces a 1-Up Mushroom if hit. The next platform has two Brick Blocks on either side with a Koopa Troopa walking in between again. The right Brick Block produces another Beanstalk if hit. The next platform has two breakable Brick Blocks and leads to another platform with a floating Brick Block. Mario can jump and hit this block, producing another Beanstalk. The next platforms are more elevated than the previous ones. One platform leads to below to a lift floating in the water. This lift is next to a platform roofed by another one above it. Inside this structure is a Switch Block which produces white coins. If forty-four of these coins are collected, Mario will have access to a White Mushroom House after the level and be rewarded with a P-Wing. On the platform above the area with the Switch Block is a stack of three Brick Blocks. The one on top produces another 1-Up Mushroom when hit. Mario then is lead to the end of the area where he must run through a Warp Pipe. This Warp Pipe leads Mario to the final area, which is a bridge across a body of water that leads to the level's goal.
