When Class Three and Mr Majeika go to the circus, it's definitely not as fun as they imagined. Everyone's a bit old, creaky and rubbish really! So when Mr Majeika casts a small spell to help the performers with their circus show, it's no surprise that Billy Balance, the slack rope walker, kidnaps Mr Majeika so that Mr Majeika can magically help him every time! Things get worse when Wilhelmina Worlock takes the opportunity to turn Class Three's classroom into a circus while Mr Majeika is trapped, and the children spend all afternoon running away from lions and alligators! But Mr Majeika's magic saves the day, and Class Three and the circus end up on the news, and Mr Potter, the headmaster, misses it all once again!
