Many Mario games feature the 1-Up chain mechanic whereby stomping an enemy once gets e.g. 100 points, then 200 etc. until some enemy (usually the eighth) and all subsequent enemies stomped without touching the ground earn a 1-Up.

The same is true for Super Mario World. However, here the variable used to track the chain is actually an unsigned single byte, which can only hold a maximum value of 255 before rolling back over to 0.

As such, if the player manages to bounce on a single enemy for over 255 times in a row (relatively easy to do underwater as seen in the footage), the chain will briefly be interrupted to go back to the scores before continuing with the 1-Ups.
