The first time I saw the Spineback Turtle card, my immediate thought was "spiky angry Lapras" hahaha XD
I'm willing to bet it's like some kind of huge, ferocious sea monster. The kind that you hear tales about, and you're like "nah, that's too big" or you just think that it's some old fishermans' tale.
The tale of a turtle as big as any ship, that will come and devour your entire crew whole. It crashes up out of the waves and decimates all in it's path.
Though, just because it's funny, I like to think that the turtle might actually be a herbivore, and it just comes up to the surface for rare occasions. It's freakishly huge and has all those sharp spikes, so it probably accidentally damages ships really bad, but it doesn't actually eat anybody. It also doesn't really go out of it's way to help the now stranded and drowning victims, but they could probably catch a ride on its back, maybe wind up wherever it is these things lay their eggs. Probably on the beach of some deserted island.
Maybe the Spineback Turtle isn't actually as huge as a ship, but there's just a giant version of it that appears from time to time. I could also see it being about twice the size of a sea turtle, and just being a kind of common monster, but it still surprises people who aren't from the area, since they probably spend a lot of their life in the water.
That being said, I bet they would make an EXCELLENT boat for adventurers hahaha :D
