Why are the Queen and King of Hatland in such a worry?
Maybe they haven't got their copy of the 'Hat Magic!' colouring book, as surely they've got their copies of 'The Little Helmet' and 'Pirate Treasure Ahoy!' the first two Hatpeople adventures, both available on Amazon.
'Hat Magic!' The Hatpeople colouring book s also available on Amazon, and has all the pictures from the first two adventures to colour!
