Grim Reaper is one of four game modes in Fat Princess: Fistful of Cake that was not featured in the original Fat Princess. This mode features a gray Warrior helmet in the middle of the map. The players race to see who can get it first. Once getting the hat, you will turn into the grim reaper (a different grim reaper than in Fat Princess). The grim reaper has 8 blue hearts and your goal is to kill as many players as possible before they kill you and collect souls(to white in the display). Once the reaper is taken down, the hat will respawn in a different location around the Grim Reaper stachue on the map. The map's name is called The Undercaker.
