When you start the level, there will be two platforms on your sides. Go to the right one. Then, just jump across the platforms without changing gravity until you see the bonus floating to the right of a platform. Hit that side of the platform and get the bonus Be careful that you have to hiy your head on a jump to get the bonus.
This level can be beaten without changing gravity, but it is incredibly difficult and is only used in speedruns.
