Hamish McHaggis is a happy-go-lucky haggis, recognizable by his orange fur, big red nose and tartan hat. In tow is the sceptical Rupert Harold the Third, a hedgehog and English gent, Angus, the mischievous pine martin, and Jeannie, the accident prone osprey.

Poppy the beetle sings all day, but her singing isn't very popular with the rest of the beetles and they refuse to play with her. When she bumps into Harry the mouse and Jake the snake, though, she finds her singing can be useful after all.

Hamish and his friends have set out to find the lost prince. But who is he and how will they find him?
