One of the levels, the World 2's Castle, mixes it with Unnaturally Looping Location, as the characters have to choose the right paths while the screen is scrolling forward and, if they miss, they'll have to replay the current section.

Auto-Scrolling Level: Quite a few of them, particularly the airship levels.

One stomped, they'll split into two regular-sized Goombas.

Asteroids Monster: The larger Goombas.

It does come at the cost of a 100% Completion, as if you cause the block to appear (by losing eight times) the stars you get on your save file won't twinkle. The player can resume control at any time, or let Luigi finish the level and then choose to either try it themselves or advance to the next stage.

Anti-Frustration Feature: Failing a level at least eight times activates the 'Super Guide' selecting it will let you watch a CPU Luigi play through the level.

Nothing happens to Luigi or the Toads, though (even though Luigi does take his hat off briefly whenever he wins). And Your Reward Is Clothes: Inverted: Mario loses his hat if you have 99 lives (he gets his hat back should he lose a life).

Air Jousting: The World 6 boss battle involves the player(s) and Bowser Jr both riding Clown Cars like the one from Super Mario World and trying to send each other flying into electric fences in mid air.
