A fable in three parts recounts the visits of seven-year-old David, with his two pets, Tod the Tortoise and Bleep the Canary, to a magical island. Here David meets extrodinary and pleasure-loving animals like Funny-Face Roo a purple kangaroo, Mello-Werrydith a crimson feathery mouse, Lola the lavender blue crocodile who speaks only in rhymes, Diego the wise and gentle dragon, and many others, not forgetting Nam the only human on the island. Each year, on his birthday, David can return to the island and have thrilling, but also chilling, adventures.
