Rubbadubbers: Back in the Bathroom! is a revival to the 2003 original series. This revival will be produced with CGI rather than stop-motion, since computer animation is cheaper to animate (though the Rubbadubbers Christmas Special will have stop-motion animation during the "If only" fantasy sequence as a callback to most stop motion Christmas specials (including the likes of Rankin-Bass)). However, it will still keep the style and spirit of the original as close as possible. It will be produced by Sabella Dern Entertainment in collaboration with Mattel Creations (currently Mattel Television).
