Okay basing this off the fact Eclipse can travel waters, what if Yn tells him they can't live in one cold and he just takes them to the warmer waters?
Heheh seahorse yn
Oh my gosh oh my gosh hhhhghghghhghg new Y/N just dropped
This would be one setting where it's not in the Arctic but Eclipse has left those waters to drift about, and look what he happens to find! A lovely little siren, hiding in the kelp.
A leafy sea dragon that can camouflage and even change colors to hide themselves in seaweed and the kelp formations they live amongst. Speed is not their forte. They also have a prehensile tail that can coil around or grasp things. They would live in deeper waters and have beautiful dark brown, yellow, and greenish hues to their leaf-like appendages over their tail with small, transparent dorsal and pectoral fins!
Every time Eclipse glides through the warm waters of seagrass, searching like a hungry shark, Y/N clings tightly to kelp with wide, terrified eyes. They watch him drift closer, hoping against hope that their tail colors have shifted enough to blend them into invisibility. But, somehow, he always snatches them out of the protection of the underwater forest and meadows. Y/N cannot run away, they simply lack the agility and speed, so they're stuck once Eclipse has his hands on them.
Y/N gets used to Eclipse's grabbiness—it's strange to interact with an apex predator that doesn't want to eat them (at least not right away.) They will relax enough to let Eclipse pull them along, his pace so much faster, and even coil their tail around him when Eclipse decides to stretch out on the seagrass for cuddles.
Y/N's leafy appendages are a great source of awe and admiration for Eclipse, and Y/N has never seen such a black and white fish like him before, especially not in their home. Eclipse loves Y/N's slow and drawn-out singing. Y/N doesn't often sing, especially when he's taking hold of them, but he'll keep his hands off just to let them echo a few notes while weaving in between the long kelp strands. He'll follow, much less graceful in the watery forest, but he never loses sight of them.
