Build a Ship with Kate and Harry ($0.99 ? Free, 34.8 MB): Your little one can let their imagination run wild by designing ships with Kate and Harry. They first get to decide if they want Kate or Harry to be their helper. They can then craft their own unique ship by tapping on different items. When they’re ready for an adventure, Kate or Harry will man the ship and sail it through randomly generated and interactive environments.
