Ever since Amira and Dylan had discovered Leonard the dinosaur sleeping at the bottom of Horsmarlonerpool Harbour by accidentally tickling his toe, the huge creature had not only been wide awake for the first time in millions of years, he had also been a huge help.

He would scoop the muck out the bottom of the harbour so the biggest ships could sail in to nice deep water. He would move boats around by gently picking them up and placing them back down where they were needed. And on a still day, if a boat with sales needed a helping hand getting back out to see he would blow very gently - and their sales would fill with air and zoom the craft back out to sea as all the sailors held on and laughed.
