Two cats, Ziggy and Natasha, make their way through Hallowe'enland to meet King Iggy, of the Enchanted Island. Ziggy is King Iggy's only son and he wants Ziggy to leave Catlandia and stay in Hallowe'enland.
Mistakenly thinking that Ziggy was abducted, house cat Rosie sneaks out and follows them into Hallowe'enland. Soon she befriends a harvest mouse called Herkimer who must help her get to the Witch Queen and the Castle with the Pink Door.
Through their journey, the cats meet witches, scarecrows, skeletons and a six foot leprechaun!
