Jalapeno Harry is a cancelled platform game that was in development by Sony in 1997 / 1998 for the original Playstation. There is not much information available on this unreleased project, except some concept artwork that shows what the game would have looked like. We can read some more info about Jalapeno in this quote by Jason Rubin on IGN:
Sony even started to mess around with its own, internal platformer based on the success of Crash. “Because Universal owned Crash, before Sony bought Naughty Dog, Sony thought that in case Crash went away, they needed to have an engine that could do what we were doing,” Rubin said, “and they actually internally started working on a ‘Crash Killer,’ they called it, that was eventually Harry Jalapeno, believe it or not.”
Maybe Sony decided to stop the work on Jalapeno Harry as Naughty Dog and Universal made the Crash Bandicoot series a Playstation 1 exclusive and they did not need to spend money on another platform brand.
