It would be really awesome if all "Game Prize (160)" rarity balloons were accepted at the Carnival. Currently, they only accept balloons that used to stock at the Lakeside Balloon Hut. But there are other "Game Prize" rarity balloons that I'm sure would love to be donated to the Carnival.

These come to mind immediately.

It's too late to do it after users spent a lot on the retired balloons.

I agree. I stopped donating at 500 once I got the forum title because it would be too pricey to go for the 1000 achievement, but it wouldn't be so bad if other balloons were accepted... especially the Random Balloon.

I also REALLY wish Holiday Item (175) balloons were accepted too, since some of those have little value (especially the New Years ones). Or at least that Quentin asked for them when they asked for other holiday stuff... Since I decided to only keep one of each balloon in my gallery, I have a lot of extra balloons floating around. (Floating... haaaaaa.... ugh balloon puns.)
