I'm glad you enjoyed the challenge! I was worried people would find it too harsh.
Polly will be playable in a future update! When I have the art assets done, she will for sure max out when giving her the potato :)

I can respect the challenge, because it depends on the player's actions, but just in case if enough people said it too difficult or not enough time, just make it last a little bit longer.
Speaking of art assets, when will there be more for Gigi? Because I think there no immobile art and missing one or two inflated art state.
Other than that, can't wait to see more art for Polly, along her being playable!
