Deadly Danger Dungeon

Overview
This stage is riddled with spike pits, traps, healing tiles, and all that sort of psychotic stuff. You can collect a key to get to the door near the start panel and go to the other door. It's filled with light platforms aside from the middle chunk of terrain. You can walk up or down foreground paths by moving up or down on them.

Hazards

 * Some light platforms are ghost platforms and one of the sections that measure at the same size as a stage builder block is a ghost platform that drops you down, working like a 3D plane rather than just 2D.
 * At the edges of the large chunk of terrain in the middle of the stage, it manages to make you trip you over into a spike pit in the background. When you just land on that space, you'll be in front of the spikes.
 * Arrow cannons in the background will shoot at you, even (everybody now) in the knees.
 * Depending on the panel you land on, you take damage.
 * Rocks will fall from the ceiling on occasion.

Kruel KO(s)

 * (Between Door B and Door C) The opponent slides down the slide and into a pool of lava.
 * (On the left where there's what looks like a foreground path) The opponent is slammed into the wall and is fed to the crocodiles.
 * (In front of Door D) The opponent is mauled by a slide of spikes, then falls down one of the ghost panels into the spike pit.
