OH NO! Captain Barnacles is missing!

At 8am this morning, Captain Barnacles was out in Gup A on a solo mission, checking on the local coral to make sure it has enough zooxanthellae (that's algae to you and me).

Suddenly, an undersea storm swept him up and carried him far away!

The rest of the Octonauts are worried about where he's got to and need YOU to step in as Captain for a day.

You'll learn lots of cool stuff about the ocean and how to protect it along the way.
