Bear doesn't like visitors. He even has a sign to warn them off. So when a small, grey, bright-eyed mouse appears on his doorstep while he's making breakfast, he is furious! And when the unwanted guest turns up again in the cupboard...then in the bread drawer...and then in the tea kettle...Bear is beside himself! But it seems the cheeky mouse is determined to stay for tea - and it isn't long before Bear is begging his new friend not to leave...
