I am disagree with some comments of the users of this movie because of the very bad dubbing of the movie. We have to remember that, for a Mexican movie, this one is on the standards of this time (beginning of the sixties) and it had to be see it more as a theatrical way than a movie.
The most appreciated character on this movie and the next two had been made is Manuel "Loco" Valdes because he was in his top moment as comedian and actor, so he develop a very funny and unoffensive wolf that became the pivotal of this and the next two movies.
Maybe for me, this movie is now not more than a lot of sugar on screen (currently I am 27), but for the time I saw it (around 20 years before), this series of movies became a very nice experience to see on Mexican TV.
This movie is good for kids that wants to imagine that the characters are real even that they look so unreal on screen, but forget to hear it dubbed in English, the Spanish version is better.
