@Bluespade: I've seen a couple of explanations. One of them is that she's good at using bubble wrap, another is that she's good at manipulating air currents, another is that she's good at diving (underwater) and another is that she's good at making bubbly chemicals.

Quick; somebody shake her!

Now I'm envisioning Derpy rocketing along with a hissing sound, bubbles streaming from her ass...
Me am smart. Dont yu wish yu was smart liek me?
Oh come on.
