Marina was a mermaid that Handy had first encountered in the episode "Handy's Sweetheart". He was busy testing out his deep-sea diving equipment when Marina, who was attempting to jump up the waterfalls of the Smurf river to find the cure for her ailing father, ended up drifting downstream unconscious straight toward the Smurf river bridge. Handy rescued and revived her in a special pool that kept her oxygenated, then with the help of his fellow Smurfs brought her father from his underwater kingdom of Atlantica to the Smurf Village while also collecting the cure from the Pools of Avalon. Handy fell in love with Marina, but because she was a mermaid, he was unable to keep her with him in the village, and she was unable to keep him with her in her underwater realm. Eventually they parted ways, though they continue to encounter each other from time to time.
