'Mr Mo was a little monster. He was soft and squishy and not a bit scary.
'Mr Mo spends all his time with his best friend Jane, singing songs, doing magic tricks and sometimes making mischief. But one day, Mr Mo starts to grow.
'He grows a little more, and a little more, until he is so worried about becoming big and scary that he hides away.
'They are both so sad on their own - but Mr Mo soon realises that even big scary monsters still need their best friend (especially during very loud thunderstorms).'
