The Devil in the Deep

When Necksa, lord and ruler of the sea elementals, declares war against the air-breathers for their constant pollution of the seas, the Ghostbusters are hard-pressed to stop him before he drowns the city. But things get worse, when Egon, Ray and Winston are swallowed by Necksa, and Peter is left alone to stop the monstrous behemoth on his own. Janine also spends the whole episode in a bikini.
