Did anyone else notice the word "TUBE" in the order section? Maybe carrying tubes again, or going through them like tunnels.
Also with the scanned idea. since one fish is in one direction and the shadow is in the other maybe a reversal go direction?
I liked the moon idea with the uneven playing field. Or a round playing field.
