Casimiro y el horrible monstruo

This is one of the most enjoyable and endearing little cartoons ever turned out by Chuck Jones, simple and unpretentious bits of humor that come about all because a "bookworm" invades a bookstore where Sniffles the Mouse is on guard watching out for the classic books.

Various characters from the books join in the fun, and mayhem erupts when someone awakens the Frankenstein monster. The merry chases are fun to watch and Sniffles manages to resolve the situation at the predictable end by disposing of the monster.

The last scene involves a happy reunion between Sniffles and the little green bookworm. The animators do a great job of giving the mouse and the worm warm personalities. Kids should find it delightful.
