“Oh, well, what’s a proper bouncy show without another balloon or two floating around? Besides, you’ll have so much fun wriggling and squeaking about as your rump floats up in the air between sets, and you’ll be a lot more fun to bap about while I’m singing, too! Besides, you’re gonna have to get used to being all floaty and bouncy for the grand finale… hehee, oops, spoilers!”
“M-meep~”
pfwoosh!
Oh my, seems that some of the prep that parade blimp mentioned involved getting Minty’s padding properly puffy and floaty, too! With the help of a huge tank of helium for drinking up from, he’s certainly not holding back as he uses his pudgy, squeaky belly to huff and puff that cushy rump bigger and bigger, and give it that little extra floatiness too~
