Deceased since the time of the advent of the Hunger. Many of the children of the Underground suffered their deaths at the hands of their own parents, but Monster Kid was not so fortunate. He was beset by starving Whimsun in his attempt to flee with his family to the Ruins, and was found in his last moments by Papyrus and Sans, prompting not only Papyrus' recession into insanity and the gaining of his few points of EXP, but the extinction of the remainder of the Whimsun subspecies and Monster Kid's final demise. His remains were carefully spread around the now ashen and desolate Gyftmas tree in the center of Snowdin, and it is said on the quietest of nights, you can still hear his laughter in the haunted streets of the empty village.
