ok so... in the OG crash bandicoot, the stage after you beat ripper roo... after you go through the vertical jumps like 3x there is this area where you can't go around in the back, you can't kill the bats and then go, you can't go and wait for the bats to pass, and you can't spin through the second jump spin. I did this part when I was a child but I cannot remember how... hints?
