The Fly by Elise Gravel

From chapters.ca:
The first in a series of humorous books about disgusting creatures, The Fly is a look at the common housefly. It covers such topics as the hair on the fly's body (requires a lot of shaving), its ability to walk on the ceiling (it's pretty cool, but it's hard to play soccer up there), and its really disgusting food tastes (garbage juice soup followed by dirty diaper with rotten tomato sauce, for example). Although silly and off-the-wall, The Fly contains real information that will tie in with curriculum.
