Water Monsters are enemies featured in the "Fairies in the Spring" episode of The Legend of Zelda TV series. As the Royal Water Park is nearing completion, these monsters begin appearing and scare the workers away. When Link and Princess Zelda go to the park to investigate, they are attacked by a water monster that the young hero easily defeats with his Crissword. Later on, after the duo defeat an eel that almost drowned Zelda, both the princess and the hero are grabbed by two crab-like water monsters. Once they manage to defeat them, King Harkinian arrives to the scene but is soon grabbed by a tentacle that comes out of one of the pools and drags him in, although Link is unable to find the monster or the king.
The water monsters once again appear when Link and Zelda reach the Fairy Spring. The young hero zaps them easily but this time, they regenerate. As Link the creatures, Zelda notices that the beams creating the monsters are coming from a tree and, upon further investigation, discovers that the monsters were being created by Spryte's sister. She explains that someone was draining their spring, so they were creating the monsters as a mean of defending their water supply. When King Harkinian, who was actually with King Oberon all along, explains the situation to the fairies, all is forgiven and the water monsters stop appearing so that both humans and fairies can enjoy the water park.

- "Sorry, Zelda. He's...gone, too." — Link (The Legend of Zelda TV Series, Episode 11)
- "That's right! Spryte's my sister. And you must be Zelda. And Link." — Spryte's Sister (The Legend of Zelda TV Series, Episode 11)
- "We didn't know who you were. All we knew was somebody was draining our spring." — Spryte's Sister (The Legend of Zelda TV Series, Episode 11)
- "That's right, my dear. I'm afraid our water park was hooked into the fairy water supply. And the fairy king here got worried. Perfectly natural for them to defend it, eh? [...] Not a bit, my dear! We'll just use magic ponds to move our water. Once all the pools are full, we won't need to use any more! I was just explaining that to Oberon here. He's not worried anymore." — King Harkinian (The Legend of Zelda TV Series, Episode 11)
