Crash Bandicoot - Waterfall level
This is one of a few lost levels that were scrapped early in development. They're all unnamed and unfinished, featuring themes, enemies, and mechanics not seen in the final game at all, as well as lacking crates and pick-ups. They were cut very early on, so even though they're still in the prototype's code, the only way to access them is with a hack.
It's a mostly vertical level in side-scrolling fashion.
Beginning
You start out in a spot that resembles the river levels. There is an untextured platform in front of Crash that leads to a similarly untextured rocky wall. Crash must go there and climb it.Hyena
(contributed by Guy)A hyena stands in the way. This enemy is solid and you can stand on it, but it has no animations and it doesn't hurt Crash, nor can it be defeated. It's nowhere to be seen in the retail version and was likely scrapped before they could do anything else with it.
