One of the best ones you've done so far in my opinion.
Both Amber's and Bobi's reactions are great to the mess that they each got for each other, and that curry sauce was a tat bit nasty for someone who's still new-ish to the world of wet and messy, however on the other hand the reactions are pretty funny towards it.
Goopermarket sweep is definitely my favorite game you play on gungetank girls, so keep up the great work.
Think the swapping was a bit unfair, as the one who didn't buy the curry sauce did a better job on the other ingredients. I suppose, in theory, it would pay off later...
The gunging at the end was spectacular. I've never seen anyone so covered in such a short space of time. The loser couldn't have been any messier had she been dunked GYOB style. Helped perhaps by her not being able to see the gunge gun assault as she was too busy with the overhead drop...
