Chema is an adult human who appeared in the series' second period, from 1983 to 1987.
The apron always shows flour stains, even when he is opening the bakery in the morning, supposedly coming from home.
Chema even has his own solo songs, including "Panadero Soy" ("I Am a Baker").
Juan Ramón Sánchez has appeared as Chema in live productions of Barrio Sésamo since 1987, alongside actress Chelo Vivares as Espinete and José Riesgo as Julián.
In the TV series Aída, Pepe Viyuela plays a gentle shopkeeper named Chema in homage to this character.
