Voyage to Mermaid Mountain

Pixie has lived with her eccentric grandma ever since her parents were lost at sea, but when she learns of a wish-granting mermaid, she sets sail on a pirate ship with Nanny Monkton, her friend Wyld and his pet talking frog, Pebbles, so she can wish her parents back.
With the help of a magic coin, they travel the high seas, encountering shipwrecking storms, an island run by cats and a giant, friendly seahorse, but will they reach the mystical Mermaid Mountain in time? And can the mermaid’s magic finally wish Pixie’s parents home?
