We've known Finn was a comet for a while, but we never really knew what he would look like in the interrupted state that we saw the purple comet in. I pulled from two sources for this- the cuts that the grass sword makes on the candle in Blade of Grass and Warren Ampersand's planet as to imply maybe something with his race and Finn's past life, in typical Adventure Time seed planting fashion.
