To quote the original DA description:
"The game shown here might be found at some sort of tickling-themed fair or amusement park. The rules are simple: four participants have their feet locked in stocks, with rolling brushes at their soles. The speed of the rollers is controled by the weighted pressure plate n the middle - when the game starts and plate is empty, they move at measly 10 RPM; however, a candy dispenser mounted above the contraption slowly drops its load on said plate at one minute intervals, causing an increase by 5 RPM every time. Every set of stocks is also equipped with a "chicken" button; pressing it will stop the connected roller, but still keep the participant locked. The game continues until all four buttons are pressed, at which point the dispenser stops and the participant who pressed their button last is released and can take all of the candy on the pressure plate as their hard won prize... as well as have some fun with three losers (and yes, this includes simply setting them free, but we all know that's not happening :p )."
Notably this was my first ever drawing of a Noibat, who soon came to be one of my go-to lees. Really, I think it deserves way more tickle pics.
