What if you could make a chalkling that could think?
Life is made out of cells. Each of the cells in our body are relatively basic, having only a few simple functions. When combined with trillions of other cells, they make living organisms which are able to act and think independently. It would be easy enough to draw a 'cell' chalkling, and then give it the commands it needs to contribute to the system. If you practiced enough, and used small enough chalk, you might be able to get the shape down to (random estimate) the size of a dime. Then if you repeated this process trillions of times, keeping them close together and connected all the cells to each other, you could make a brain. An insanely massive brain, but a brain all the same. If you could accomplish this, would it make a sentient chalkling?
EDIT: Google puts the size of a dime at 18mm. Therefore, the area of one cell would be 2.54 x 10^-4 km². Multiplied by 37 trillion cells in the average human body, the surface area the chalkling would cover is 9398 km². That's about the size of Jamacia. Which is smaller than I thought it would be. But that's for the whole body. There's only about 100 billion cells is the human brain. So just to make the brain, you'd need an area of 25.4 km². I'm not sure if you'd need other organs like the heart as well to make it work, or if it could survive on its own.
