Pigs by Robert Munsch
Follow the misadventures of Megan, who lives on a farm, but who disbelieves her father's advice about the intelligence of pigs. She shows them an open gate. They escape and follow her - into her house, into her school and onto the school bus -and take over her life with disastrous and rumbustious results! Master storyteller Robert Munsch was telling his tales at a school visit some years ago and a girl named Meghan asked him to make up a story about the animals on her farm. This is that story!
