Welcome to the world of Mini-Jon! Mini-Jon is actually a clone of Jon Le Bon. A curious little guy with mischief enough for three, Mini-Jon has a unique talent for getting into trouble! Every moment is an adventure when he's around. Step into a fantasy world where humour and science come together in an explosive mix. Henry tells Mini-Jon and Mini-Maple, who are alone at the Agency, that the Munch Monster will visit them if they don't go to sleep soon. But the two friends know that there is no such thing as a monster that gobbles up toys and candy ... right?
