Underwater

Underwater is an AU where Undertale takes a plunge into a captivating underwater world instead of the Underground's familiar setting. Here, the monsters, once banished, find themselves submerged in the depths of the ocean, separated from civilization by a formidable, magic-proof barrier. The underground's creepy hues and textures are replaced by the vibrant blues and watery depths of the sea. The characters, now adorned in water-themed attire, navigate through coral castles, trenches, and kelp forests, adapting to their new aquatic environment. The underwater journey unfolds as Frisk, adorned with determination, explores the mysteries of the ocean, encountering unique challenges and forging bonds with sea-inspired incarnations of familiar faces.
