This week, we're setting sail with Disney Cruise Line to visit Disney Lookout Cay, where the native sea creatures are so beautiful and inspiring that Duff Goldman and Kardea Brown ask the bakers to create sea animal desserts in an ocean or beach setting. For the twist, bakers are required to make a custom ice cream with a mix-in that goes with their dessert. Then, very special guests Captain Mickey Mouse and Captain Minnie Mouse drop by for a visit because there is an amazing prize at stake in this challenge -- the winning baker will enjoy a Disney Cruise Vacation!
