For example, when Mario is less than 160 units below the nearest ceiling, he is considered to be "above" the ceiling, his vertical speed is killed, and he bonks. If Mario moves to a positive (upward) vertical PU, the "nearest" ceiling will be determined based on truncated coordinates, and will therefore be in the main map. But when checking whether he is above this ceiling, floating point coordinates are used instead, and so Mario behaves as though he is stuck in a ceiling. This behavior results in positive vertical PUs appearing to be filled entirely with ceilings.

On the other hand, when Mario is below his "nearest" floor, he will snap up to it. This means that if Mario moves to a negative vertical PU, he will usually upwarp back to the main PU grid. This is called an '''Overflow Jump'''.

It is typically difficult to get to a vertical PU. In the positive direction, there is a ceiling at ''y'' = 20,000 that prevents upward movement. We can bypass this ceiling by pressing against OoB, for example by using [[Hyperspeed Flying|hyperspeed flying]]. We can also use [[Platform Displacement|platform displacement]] or [[Indefinite Owl Flight|indefinite owl flight]] to reach a positive vertical PU.
