The Lumpy Space People are characters that first appear in "Trouble in Lumpy Space." They resemble small floating clouds with hands, but usually no legs or feet and are generally shades of cool colors, such as purple and blue and in some cases, pink, violet, green and white. When the Lumpy Space People marry, they become fused together. They all have sharp fangs that can turn "non-lumpers" into "lumpies." "Non-lumpers" have their voices deepen when they become lumpy (Finn and Jake for example).
