Amy's trying to grow up fast again. This time, she saw a Dorumon skygiving while playing in the backyard. She asked Katya if she could go skydiving, but like the Jet Ski thing, Katya said she would have to wait until she was older. So it was back up to the attic for Amy. Looking through some of the less old clothes, Amy found what she assumed was a slang of sorts. But the tag on it read “Underwear”. Disgusted with how scantly it looked, but desperate for Skydiving, Amy tried putting it on over her diaper. However, the flimsy string ripped under the brute strength of the diaper's fabric.

Fortunately, there was another skimpy pair of undies nearby. With no other choice, Amy dropped the diaper and slipped the pair on. Feeling virtually naked, Amy found herself unable to pull the undies above her tails. She decided to go the way it was, hoping the lack of a diaper would make her seem more Grown up. When she confront Katya, Amy shook her hips side to side, trying to look like an adult. Katya's jaw dropped and turned pale. Amy asked what was wrong and Katya said she looked indecent. Amy is currently wearing a diaper with locks on it and stripped of outside privileges. Despite the indecency, Katya still posted a picture of her on babyfurbook and got a million hits. Amy did not get to sky dive.
