Barf-O-Rama
Barf-O-Rama is a series of children's novellas by Pat Pollari, the pseudonym of the popular children's author K.A. Applegate (who also wrote the "Animorphs" series). The stories were humorous, with a strong emphasis on scatological humor and other generally repulsive themes. The humor contained in the series is similar to that of Sylvia Branzei's Grossology series or the Slimeballs trilogy, by U.B. Gross. Because of the limited availability of many of the books in the series and their relative obscurity, most of them are out of print and very difficult to obtain
