Navigate number skills on a pirate adventure with Tad, Lily, and Scout! Tad and Lily need a little number sense to help them get through a complicated game, so their magical firefly friend, Edison, takes them on a fantastical journey under the sea! When their cute puppy pal, Scout, is mistakenly captured by a pirate, they must use their new understanding of numbers, counting, and estimation to rescue him. Join them as they navigate the deep and face foes such as sharks and crab henchmen--even Pirate Pythagoras himself--and begin to see numbers in a whole new way!
