It’s World Book Day and school is full of kids dressed up as their favourite literary characters and celebrating the magic of reading. But something smells funny… in every classroom, there’s a teacher letting go of a long, loud, ground-shaking, ground-breaking fart. And when our hero spots a fellow pupil (dressed almost too convincingly as an alien) hovering by the teachers’ bums, and then discovers what looks like a spaceship powered by farts behind a hedge, he’s on a mission to stop some unexpected visitors from kicking up a massive stink!
