The Elmo's World Boom Box from Fisher-Price is an anthropomorphized stereo, with blinking eyes and a smiling crayon antennae. The Elmo's World characters adorning the toy include Dorothy, Elmo himself, and a Mr. Noodle (most closely resembling Mr. Noodle's brother Mr. Noodle). The boom box's audio selections include Elmo's voice, sound effects, and six songs.
