Mutant Mantis Lunch Ladies!

Best friends Carlos and Benny, who just saved their teacher from becoming a were-hyena, have been called upon to investigate the strange goings-on in the cafeteria. Why are the lunch ladies suddenly so grumpy? Why are the girls' meals different from the boys'? And what was that thing seen scuttling around the kitchen wearing an apron? It's going to require a lot of courage--and more than an industrial size can of Raid--for the boys to avoid extermination in this buggy adventure.
