Here's a fun little Android kids app that takes things under the sea. Scott's Submarine is an interactive book that tells the story of two children, Scott and Aiko, and Scott's cat, Jazz, and their underwater adventures.
Each page has animation on it, but no so much that it's distracting. Every few pages you search for items, which gets a little more difficult as you work your way thorugh the story. And there are two levels of reading -- 2- to 3-year-olds, and 4 and up. The former uses smaller words for younger children, and the latter uses a more advanced vocabulary and longer sentences. The reader's accent could be a small issue for some children, however.
The 37-page story also got four languages -- English, French, Spanish and Japanese -- and costs $2.99. We've got download links after the break.
