Paper Mario: The Thousand-Year Door - Battle vs. Whacka!

After completing the main story, defeating Bonetail, and causing the extinction of the Whacka on Keelhaul Key, Whacka will be unlocked as the true final boss of the game at the end of the Pit of 100 Trials. The fight is pretty straight forward. The more you attack Whacka, the more Whacka Bumps are dropped with which he'll use to either retaliate or recover. Red Whacka Bumps will pierce defense and do loads of damage, so try to Super Guard as many as you can. With this I have 100% the game :D
