Kaizo World

Overview
A stage of hell and trollings for even the most insane to overcome. Few have ever tried to get through the hazards involving spin-jumping Nibblers, Pokeys, passing lava, and seeing where the hidden blocks were located. And now, it's converted into this stage consisting of a thick layer of clouds, ground alternating between bottomlessness, lava, and Nibblers; Thwomps falling from the sky, and there are even platforms in the form of hidden blocks.

Hazards

 * Lava
 * Nibbler Pit
 * Thwomps from out of nowhere, but they can be stopped when you're under a platform of hidden blocks
 * Expect there to be Brutal Kirby saying hi in the most vile manner way possible

Music

 * Super Mario World - Castle Theme (Project M)
 * Brentalfloss - MegaMan 3 Game Over (to remind everyone how much Kaizo levels will bite you in the ass)
 * Super Mario Hyadain
 * George Clinton and the Goombas - Walk the Dinosaur (given that this is John Luigizamo's stage)
 * Super Mario World 2: Yoshi's Island - Giant Baby Bowser (increases the likelihood of Brutal Kirby)
 * myuuji - Luigi's Mansion (not the most fitting remix, but again, John Luigizamo owns the stage)
 * ChEsDeRmAn - Super Mario World March #3 (it IS Super Mario World; BTW, raise your hand in you heard this in ChunkyMonkey4U2's Super Mario Flash 2)
 * Super Mario Galaxy 2 - Final Bowser Battle (such an epic theme somewhat wasted for a less-than epic boss fight)
 * WaterFlame - Race Around the World (athletic daytime in AKR2)

Kruel KO

 * The sucker gets stabbed in the back by a fuse, then nearby blown up before Luigi knocks him/her into some lava.

Extras

 * Some of the clouds on the platform either fall or can be dropped from.

Trivia

 * Race Around the World was one of the tracks in A Koopa's Revenge 2, in case anyone were to ask.
