Toy Island produced a set of triangular Sesame Street crayons in 2010. The crayons are sold in two-packs, and in an eight-crayon set.
Each color is matched with a Sesame character -- Elmo (red), Abby Cadabby (pink), Ernie (orange), Big Bird (yellow), Oscar the Grouch (green), Cookie Monster (light blue), Grover (dark blue) and Count von Count (purple).
