Now Go To Sleep!

The kids from Mrs Moo's class are running wild - it's bedtime, but none of them can sleep - one's had too much sugar, another is afraid of the dark, one can't put his game down, one read a far-too-scary bedtime story and another - a crocodile - actually just has too many teeth to clean! In each house on Sparrow Street, the grown-ups are repeating 'now go to sleep', but nothing is working.
