Linda DeMeulemeester probably never had an animated series in mind when she wrote her first Grim Hill book. But once the first was deemed a success, and a sequel met with a similar reaction, the train kept rolling! Now, with 5 titles in the franchise, Wizard Hat Productions wanted to jump in to ready a CG animated series based on the adventures. The tale mixes Celtic myths with faerie lore, with Cat, Sookie, Jasper, and Clive live their regular teenage lives while fighting powerful, mythical creatures. Wizard Hat has been crafting the look of the series with guidance from Pam Slavin, Toni Stevens, and Bill Fox, who formally worked at Cookie Jar Entertainment.
