Oso is trained by Wolfie to go on a deep sea search. Oso is to launch a deep sea probe in an underwater cave, but he launches it in the wrong direction and hits Wolfie's boat. That's when a special alert is called. Oso shows Athena, a girl at a school playground in Greece, how to drink from a water fountain. That way, she wouldn't be thirsty anymore.
The episode's title is a reference to the James Bond title Die Another Day.
