Once, you've gotten the Pixl named Dottie, travel back to the Land of the Crag (Chapter 5-1). As soon as you enter the area you'll be on top of a stone platform. Go all the way to the right of the screen. Go into 3-D and use Dottie to enter the small opening in the wall.

Once in the secret area you'll go down a pipe and collect a bunch of coins (hit A to see more coins) then exit out of the other pipe. Once you leave the pipe, walk to your right and a little creature called a Whacka should appear. If you jump on his head a Whacka Bump will come out.

These give you 30HP and if you go back into the pipe and come back he'll reappear. You can get about seven or eight Whacka Bumps before he disappears for good. That's at least 210 HP for free.
