Pan mae awr-wydr hud yn ymddangos yn ei fwthyn, mae'r Bwbach yn sylweddoli bod helynt ar y gorwel. A phan mae dewin tal mewn clogyn coch a'i gynorthwy-ydd Colin y Coblyn yn cyrraedd, mae'r Bwbach yn sylweddoli bod yn rhaid iddo gasglu creaduriaid hud Tai Ffagan ynghyd i achub ei ffrind gorau, Mari. When a magical hourglass appears in his cottage, the Bwbach predicts there's trouble on the way. His fears are confirmed with the arrival of a tall wizard in his red cloak, accompanied by his assistant, Colin the Coblyn. The Bwbach realises he must rally the troops of magical creatures of the Houses of Ffagan to protect his best friend, Mari.
