A Dark Dayzee is an enemy that appears in the game Super Paper Mario.
Dark Dayzees are stronger, darker versions of Crazee Dayzees and can be only found in the Flopside Pit of 100 Trials. Dark Dayzees, like with Crazee Dayzees, attack with a singing attack that can travel a good distance. Dark Dayzees are very powerful as they have more HP than even Amazee Dayzees. Using Bowser is the best way to take them out.
