Creative Prompt: Hello Crab Camaro! I did a bit of digging based on your location of Concord New Hampshire and can tell you that you are probably dealing with the Atlantic horseshoe crab based on the ranges of the four extant species of horseshoe crab that I was able to find. The bad news for you regarding them is that they have a pretty good range of survivable temperatures so short of setting the car on fire or towing it into a refrigerated environment you are unlikely to be able to deal with them that way. Admittedly if you are comfortable setting fire to the car that would be the easiest way to go about solving the problem and I think a good fire is worth wasting your Camaro. On a positive alternative option though I did discover that they can only survive out of water for about four days so if you can dry out the car for a week you should be able to effectively starve them to death and be good to go other than clearing out some corpses. From there we all have experience cleaning out dozens of corpses from our car right? Best of luck to you Crab Camaro!
