In middle of a challenge game with Sylvie, you challenged her to blow herself up like a balloon with her thumb and bob in place for the longest amount of time possible, challenge she accepts just to keep messing with you, but now as an inflated girl.

She inhales enough air before placing her thumb on her mouth and blow on it, causing her body to inflate like a balloon and lift her off the ground, her body sways gently as she floats in place.
