S1E4 The Earthquake

Vanessa and Jason set out on a boating mission, but Neri cautions Jason about an impending earthquake, prompting their quick return. Commander Lucas is furious, but soon enough, the earthquake strikes. Meanwhile, Damien and Lee find themselves trapped in a room that’s starting to flood. In an effort to rescue them, Froggy uses a clever computer program named HELEN, which stands for Hydro Electronic Liaison Entity 3000, to try and help them escape from the rising water.
