A scribble is a drawing composed of random and abstract lines, generally without ever lifting the drawing device off of the paper. Most often, a drawing is considered a scribble when it is on paper that already has a drawing and is meant to be colored in, such as in a coloring book. Scribbling is most often associated with young children and toddlers, because their lack of hand-eye coordination and lower mental development often make it very difficult for any young child to keep their coloring attempts within the line art of the subject.
