super-fun diversion for pre-school children, this sandbox adventure is all about populating ocean environments with various animals, then absorbing fascinating facts and exploring their habitats. You can also build boats and submarines to get you around your watery world. It can be a bit too freeform in places, so we’d like to see more prompts and direction in future updates, but for now there’s lots to keep creative, inquisitive minds occupied. free / iOS
