 In each program, four famous people were competing to guess words that were explained by small children with their vocabulary (and the difficulties it gives for the contestants to guess the word that way). When a contestant guessed the word, he earned a strange puppet called "Gallifante". At the end, of the program, the contestant that had earned the highest amount of gallifantes was the winner of the day. In the second and last season, Javier Sardá made his debut on TV after some succesful years in the radio.
