I want a stage which is so cool everybody would want to play on it. I'll give an example.
You start off on a big flat platform, with in the background the intro to the SMB theme, but it still sounds familiar to something you already know.
Then the whole background is going like weird, as if someone has taken too much LSD. Then you hear the famous words:
Swing your arms from side to side
Come on it's time to go
Do the Mario!
Take one step and then again
Let's do the Mario
All together now!
And it loops infinitely. Meanwhile, the whole stage grows mushrooms, the platforms disappear little by little, and then you only have ground on the floating mushrooms. After that, you see a bunch of non-object starmen on which you will need to jump in order to survive. In the background you can see Captain Lou Albano as Mario with an evil smile, and ocasionally you can see Danny Wells as Luigi, saying "Oh oh, Mario." and also you can ocasionally hear "OH OH" by both when a player dares to fall.
To get back on the stage itself, you now see floating carpets, and see warp pipes floating below you. While you are still on the Starman, you can also see a head of Link saying "EXCUUUUUUSE ME PRINCES".
When you still survive the playing, and not die from a stroke, you can see lots of Toads running across the screen. Afterwards, a Pirhana Plant grows up, Bullet Bills blast from either sides, the Starmen disappear (which is alright, because they assume you'll land on a warp-pipe anyway), and you will be treated with falling King Koopa statues.
And if you thought it doesn't get weirder, you'll see some Bob-Ombs walking your way from either sides, which explode directly on contact. They're hard to avoid simply by their size, so it's a guaranteed knock-out. Then a lot of Birdo's go run around in circles screaming like a girl, as if their bow was set on fire. In fect, they are. So then Mauser comes to the rescue and bombs the Birdo's. Unfortunately the Birdo's make a huge fire, and it is only when Mr. T comes by and pours milk over the fire to extinguish it.
After that, the warp pipe disappears because of the milk, and the milk hardens into the plateau, where the whole thing loops again.
What do you say? It would be like the ultimate stage.
