At the difficulty select screen, whip all the hanging skeletons and both snakes to receive a 5,000 point 'Completion Bonus'. Whipping all the gas cannisters in the cage stage gives a 'Pyro Bonus' and whipping every bone pile and snake in the altar stage gives a bonus also. When on suspension bridges over lava flows, whip enemy guards until they fall in the lava for additional bonus points!
