I stumbled upon this by accident years ago while messing around with my Lion King SNES cart (still have it). What's weird is that the HooHa song that's played on the Simba's Return level has this hooting sound that you'd probably hear on the African serengeti or something. It only happens for a short bit, but it's an interesting thing to hear, and sometimes I think that the other version sounds better than the one used in the game.
What you'll hear on the video is the original HooHaa before you hear the different one.
Please don't ask for the rom. I won't give it to you. I you have your own rom or original SNES cart then try it! I have no idea if this happens on the other tracks or the PC, NES, or Sega versions, so experiment!
