I've already started a draft, but I need quite a bit of time to expand on the file and thought I'd go with something a bit simpler before I finish it, so here's an idea:
The SCP would be a snake, most likely a species of boa. It would look pretty much exactly like a regular specimen of the species, except for the fact that it can grow a lot longer. Whenever it eats something, the length of the item is added to the body of the snake in a very short amount of time. The exact time depends on how large the food item happens to be. It's quite similar to the Snake game if you've played that at all. The SCP can survive indefinitely without food or water, but as soon as something edible is placed within reach it will act as if it hasn't eaten for a while and go straight for it. Other than that, it would act like a regular member of the species and will interact with stimuli as expected.
Any suggestions?
