Low on health? No prob. The accordion-like bushes give you a fruit if you wack them with the Grapplejack(obtained late in the game
from Mizuno, the cute witch in the Village Of All Beginnings, who lives in the first house.)
If you are low on health in the game, go to a sign post and save your game. Now hit start and choose load. Load the game you just
saved and you'll be back to full health!
