Extra power beads
The Quarter- The Docks: If you are out of power, get a large amount of extra beads by carefully head-butting (A, then X) the gator guarding the cymbals on the dock. He'll get stunned for a very short time and a bunch of beads will spew out. Collect beads and keep your distance. You should be able do this 4 times and defeat him without having to use your voodoo power.
