Lapicito (literally "Little Pencil") is an animated anthropomorphic pencil who exclusively appears in the Plaza Sesamo (the Mexican co-production of Sesame Street). Debuted in 1998, he was designed by Mexican artist Oscar Gonzalez Loyo.
In his segment, he sings his own theme song ("Hola, soy Lapicito!") to the viewer. He will randomly draw an uppercase or lowercase letter and shout it out to the viewer ("Es la letra (letter, letter, letter)") and then the segment ends.
