Owl is ready for bed. But as soon as he settles in, he hears a strange noise. He''ll never get to sleep unless he can figure out what''s going on! He looks everywhere - in his cupboard, underneath the floorboards - even in his walls. But while he''s busy tearing his house apart, he doesn''t notice one tiny, squeaky, mouse-shaped detail... Will Owl ever get a good night''s sleep?
