Millie has lost her yawn, and she can't get to sleep without it. Join her on an adventure to find it!

First of all, Millie tries to find her yawn close to home – but her pet dog and cat can't help, so she goes a little further afield. The Statue of Liberty hasn't seen her yawn, neither has the Mona Lisa, nor the penguins at the south pole, and the rabbits on the moon certainly haven’t… Eventually Millie has to head back home, but as she lies back in bed and remembers all the wonderful friends she has made, her yawn reappears and she can finally fall asleep.
