My thoughts are pretty vague (and scattered), but I believe that
this might help.
Blue + circle (from the top) + rectangle (from the side) + 5 (gallons) = something to do with the game
A cylinder is a shape that we have never dealt with yet and it is possible that they will throw something new at us. The cylinders might be filled with something for weight, though they probably wont be. The cylinders could be moved around the field strategically, possibly stacked for bonus points.
The diamond plate is on the field somewhere, as always. I doubt they will change the team and alliance format (3 v 3).
