The following year, he got to work in El Peneca. He was later signed on to work as one of the assistants to Guido Vallejos on the famous Chilean comic-book Barrabases, where he created the characters Cicleto, Cucufato and Ñeclito. In the mid-1950s, he was signed on to work on the humor publication El Pingüino ("The Penguin"). For this magazine he introduced his first truly popular creation: Alaraco, a comic strip about an over-concerned and overreacting man (modeled on Lobos' own personality). The same decade saw his work appear in the magazines Pobre Diablo, Flash, Humor de Hoy and Humanoide.
