The theme will be revealed when the jam starts. Expansion functions as a second theme in the scoring.
Roger on the theme! When you say expansion, do you mean expansion stuff ONLY such as one part of the body inflating/getting bigger, or are we considering WEIGHT GAIN as expansion too?
Weight gain and expansion are both valid! It's hard to find a solid catch-all term.
I'd just word it like Expansion/Weight Gain so people know both are valid. Thanks for the clarifications!
