I think the first question I would have is how did you even get 60 horseshoe crabs into that car in the first place? A Camaro really isn’t that big and it’s a coupe on top of that, so you would’ve had to move the front seat up unless the crabs figured that part out. I think the thing you really need to do here is push the car back into the ocean. You have to face reality here: The crabs have won. There is truly nothing you are able to do here. You must return the crabs to their home so they can live life in their new underwater home and brag to the other crabs that they have a Camaro. I would also recommend that in the future you get a better car. If you had something practical like a Santa Fe or a Camry this never would have happened. Muscle cars are a fools game.
