Mr. Penguin's Ice Cream Adventure

S2 E21: Choo choo! The team is exploring the Patagonia region of South America when they see an ice cream train loaded with ice cream. The train is being driven by a Magellanic penguin, Mr. Penguin, who's bringing the ice cream to his best friend's birthday party. But just then, the train breaks down! Not to worry, Mr. Penguin. Rocket is here! Rocket transforms into a train himself to help Mr. Penguin pull the big load of ice cream to his best friend's party. All aboard the Rocket Train! Along the way, the team and Rocket must dig to get past a huge rock, put a musical bridge back together, and chug all the way over the Andes Mountains. And just as they near their goal at last, out comes the sun! Can our Rocket train go fast enough to get to the birthday party before the ice cream melts? Never doubt Rocket when he chugs Super Fast!
