Alternative ending: Harold gets lonely, decides to draw a friend. Harold sneezes and the mouth turns into a scowl and the eyes are narrow and shifty. The friend turns into a thief and steals the crayon. Harold pursues the thief. Thief draws an open door then covers it with locks to escape. Harold unlocks the doors and corners the thief along a back alley wall. The thief draws a sanitary sewer drain then manages to slide through twisting purplish tunnels. Finally, Harold notices feint purple footsteps left by the thief near a wastewater treatment plant. Harold swipes the crayon when the thief isn’t looking. He draws a quick balloon filled with blue soot and drops it on the thief’s head from a hastily drawn ladder. The thief’s head is saturated in blue crayon. Harold quickly re-draws the mouth into a friendly smile, and the eyes into a warm and welcoming demeanor. The two smile, shake hands in an emphatic manner, Harold snaps his crayon in half and hands his new friend a crayon. The two end up up happily tracing a field where they frolic and play and let their imagination go wild.
