FantaSea is an Android game developed by Clementoni S.p.A. It is an educational game designed for children aged 4-7 years old. The game is set underwater, where children are invited to join the octopus Polpetta on an adventure to learn letters, numbers, and basic math operations.

This educational app aims to introduce children to fundamental math and Italian language skills. It features activities that are designed to increase in difficulty level as children progress through the game. Younger children will learn to observe, count, and recognize quantities and the alphabet.
