There’s no getting around it, Sid Gibbons is a little bit naughty. Just this week he’s smashed a bird bath, thrown his dinner on the floor, trashed his bedroom and left his colouring pens on the floor for so long that they’ve all dried out. His poor mum doesn’t know what to do, because when she asks him about these misdemeanours he just lies and says that his imaginary friend Kevin did it all. Kevin is invisible and no one can see him except Sid, so he’s the perfect fall guy.
Then one day, when Sid has once again been sent to bed for being naughty, a hatch in the ceiling opens and a bright light appears. Sid climbs up to take a peek and finds himself faced with none other Kevin himself – he is real! Sid is super excited to see his (incredibly cute and fluffy!) friend and they have lots of fun playing together. However it soon becomes apparent that in Kevin’s world, it is Sid who is the invisible friend.
