10. The Caterpillar Trials (2013)

Joan's pet worm Victor is being disobedient and won't get a medal at the Caterpillar Trials unless he can be trained. The Tiddlers - fresh from their assault course at Mr Bloom's fete in Hartlepool - know exactly what to do and have Victor in perfect shape before Judge Marrow arrives.
