In this game, a younger version of Ecco goes to see the Big Blue, completing tasks such as herding seahorses, swimming through rings, and finding lost balls for sea lions along the way. The gameplay is similarly controlled to the other Ecco the Dolphin games, but mainly revolves around using these abilities for solution of simple puzzles and problems. One key difference is that the player character cannot drown by staying underwater too long. Likewise, there are no enemies to attack the player character. Two other playable characters were introduced: Tara the baby orca (there is also a bottlenose dolphin character named Tara in Ecco: The Tides of Time) and Kitnee the young Atlantic dolphin, who is darker gray than Ecco. The player can switch characters at any time.
