You met a friend!
The Ocean Promise Chest ✨
Inside is not gold — it is something better: the Ocean Promise. “I promise to keep rubbish out of the sea, so turtles, whales and coral can thrive.” Every Ocean Guardian makes it. Will you?
That was Willa! 💙
Sea friends
Sea friends met 0 / 8
Press and drag anywhere on the sea — the submarine swims to your finger. Or click the sea and use your arrow keys. Swim close to a sea friend, then tap it (or its Say hello! sign) to meet it. Swim right to explore the Kelp Forest and the Deep Glow! Little ones? Turn on Calm mode — everything moves extra slowly and gently.
