Ep 15. Mechana Pegosauraus Island

The Pegosaurus over on Mechana Pegosaurus is shedding its log-sized pegs, and it's up to the Animal Mechanicals to get over there and protect the three little pigs from them! They slide over to the Island and the pegs are rolling all over the place. The team decide to build structures for the little pigs, to protect them. The first house is made from straw and is no match for rolling pegs. The second house is made from sticks and is soon flattened, as well. Mouse gets the idea to build a peg house, and Rex transforms to start lifting them into place. Unicorn transforms and uses her magic horn to create a vortex which keeps the flying pegs from smashing the new house, then Mouse has to transform so that she can quickly warn one of the pigs about an incoming peg! Soon, the mission is accomplished - except the Mechana Pegosaurus wants a house built for him, too!
