Platform(s): PC WINDOWS XP

Genre: Educational, learning game

Estimated year of release: 2004-2010 (Maybe a little earlier than 2004)

Graphics/art style: Childish 2D cartoon, or less likely less advanced 3D graphics not third person.

Notable characters: Many Fish, Maybe an octopus, Human Character (maybe a child at the very start)

Notable gameplay mechanics: Would be able to input words and test your spelling. Not story based from what I can remember.

Other details:

At the very start, you deep-dive from a submarine and are told to "bring your goggles" from a child, You are then taken to a menu with fish from all different angles and can choose what you want to do. I remember that you'd hear a voice clip saying the word "lagoon" or "deep sea lagoon". You can type in words into some list and test your self through a spelling test. I searched online and found a game named 'ocean explorers', but I don't believe that that's the game. It's missing some components like the spelling part. Would be great if anyone can help.
