It’s Midsummer Eve and Meg and Mog fly off to meet their friends, but naughty Mog is messing around and falls from the broom. Meg and friends form a search party, but however hard they look, Mog just can't be found! It takes a special spell to reveal Mog's hiding place and when they find him curled up in the cauldron, he receives a firm telling off from Meg before being flown home in time for breakfast.
