Reginald's Last Stand

Reginald's Last Stand is the final level of Princess Peach's Castle's Fifth Floor. It is a longer variant of Bowser in The Sky. You must use Stanley to enter the level. The boss fight, Reginald, is a grey evil twin of Stanley that works with Dark Matter, the boss of the Third Basement. He is a more powerful form of Stanley with new moves including shooting dark lasers, summoning evil Marios and Luigis, and draining your life and healing himself with it. There is also a second phase, where Reginald can summon dark recolors of Eyerok. Defeating Reginald unlocks the Third Basement B.
