(This story is inspired by the art and writing of Nightmareball by Lylie Punez.) A crabby morning became a day to not forget. Two friends, each struck with the terror of what the gem could bring. Nobody suffered far worse than what it had done to the peculiar feline, heart darkened by its power. With the impending force it brings, allies and foes alike, it's up to Gumball and his loved ones to end the doom once and for all.
