In a special new double episode titled 'Fintastic Fairytale', the Bubble Guppies are on a wonderful fairytale adventure. Molly and Gil take Bubble Puppy up a hill to fetch a pail of water. But when a mean Witch, played by comedian Wanda Sykes, turns Bubble Puppy into a frog, Molly and Gil enlist the help of some famous fairytale friends to undo her mean green spell. And they'd better work fast or else no one in the Enchanted Forest will live happily ever after!
