Chester is feeling a little sad and lonely because his special friend Tilda did not come out to play.

So Chester wanders sadly around all their favourite places hoping that she will have changed her mind and he will meet up with her.

Through the shop, into the school, past the scary dinosaur park Chester goes, and still Tilda is nowhere to be found.

But when Chester gets home he hears some very funny sounds and has the biggest surprise of all.
