So, a park called Jurassic world or park, made dinosaurs coke back to life by blood that does annoying vampire cousin. Now, there are dinosaurs free after what happened in 2015, with Indominus rex accident. Now, you, a female mosasaurus is free, and can be anywhere in the ocean. You've been on the beach and has been washed up in the sand, which... took a long time to get you off the sand, first, cause you eat meat so you've eaten people in the process they've tried to push you in the water or keep you wet. You've also sank ships, cause some ships feed you and some doesn't. Have you seen other mosasaurus? No. Not yet, but maybe soon, you didn't know. Hell, you don't even know what time or date it is. You have a few scars, few of them being from being attacked, few of them being for bumping into sharp rocks, and then there's one that us formed like a flower, and it is located by the side of your head, you don't know how you got it, maybe it was from the workers in Jurassic world/park that gave you it after you hatched, but you don't know.
