Mitchell is bitten by a rabid Deputy Head and, every time the school bell rings, transforms into the disciplinarian were-teacher, Mr. Tanner. If the curse isn't lifted before Mr. Tanner signs a permanent contract, Mitchell could be doomed to spend the rest of his life as a teacher at Strange Hill!

When Templeton's Science Fair attempt to blast into the cosmos backfires, he accidentally instigates a full-blown alien invasion - by aliens that seem remarkably familiar and have come to pay homage to the creator of the Universe...Templeton?!

Mitchell must pass the 'Hardest Maths Assignment Ever'. He cheats and ends up earning the mythical grade of 101%, breaking maths and the world as we know it in the process.

When Becky coaxes a wilting plant back to life in the old Strange Hill Greenhouse, she gets more than she bargained for with an outbreak of plantlike PE teachers threatening to exercise the world into submission. Only Mitchell's sarcastically planted chicken nugget beast can save the day.

A new school security system is installed - and the cameras seem to record what happens in the future. When Templeton becomes Security Monitor and goes mad with this incredible, all-seeing power, the very existence of Strange Hill is threatened.

It's Aprils Fool's day and Mitchell is pranking in overdrive. Before too long he's pranked everyone and unleashed a dormant beast of Embarrassment that lives under the school. Mitchell must save his friends - and Tyson - from 'The Embarrassment's' disgusting lair by going toe to toe in a shameful game show.

Mitchell accidentally erases himself from history after deleting his school record. At first his anonymity is fun but when his friends forget him and he starts to disappear, he calls on Samia, the one person who can remember him, to help reboot his existence.

It's Valentine's Day and whilst attempting to sabotage Abercombie's zero tolerance to romance, our trio discover a portal to the inside the Head's head! What at first seems like the best thing ever soon turns into a nightmare as the bullies gain control of the Headmaster. The only way to stop them is to test the old adage: the heart rules the head.

During a swimming test in the middle of winter in the dreaded Strange Hill swimming pool, the kids discover a mysterious paradise island in the middle of the pool. They also soon discover the isle's longtime sole inhabitant, a mysteriously huge exchange student named Ken Kong. When Ken returns to the school with our kids, it throws Abercrombie into a panic. Will Ken destroy the school? Will Templeton's woodwork project save the day? Will Becky guilt Mitchell into fixing the problem? Probably!

When Mitchell is issued a strange simulation baby doll to teach him responsibility, his first reaction is to bin it. Freakishly it keeps coming back and he soon realizes it's alive! From apathy, to panic to parenthood, Mitchell soon appreciates that having Mitchell Junior around might not be so bad after all.

Mitchell, Becky and Templeton stumble across an underground lair that was home to a league of medieval superheroes - Ye Olde Righteousness League. When the League's evil arch nemesis escapes his confinement and possesses Abercrombie, our trio find themselves (and their classmates) transformed into these heroes to fight his tyranny.

The Annual Strange Hill Festival is approaching. Not staying quiet about his dislike of folk music, Mitchell drives Miss Grackle mad - and perhaps to an early retirement - and the kids get a mysterious and oddly nice new music teacher who may have a much deeper connection to the ancient Spring Festival than anyone realized. It all leads to a furious musical duel between Mitchell and his friends and an ancient force of corny, irritating music.

Mitchell's desperate attempt to start his Christmas holiday early is scuppered when he accidentally traps everyone in the freezing school. Forced to spend the holidays together, the students and teachers soon discover mysterious things happen at the school over the Christmas holidays, things involving Santa, menacing elves and as Abercrombie goes mad, a very cheery parody of "The Shining".
