It depends if she was inflating herself on purpose. If she was, I'd probably say something like "you do that too?! Can I join in?!" (Because I practice real life inflation.)
If it was some horror thing, like someone was trying to kill her, I'd get her out of that thing as soon as possible.
Hmmmmmm id have to take her home and keep her as my little (or rather big) plaything. Would mind if it was Rhonda Rousey :-D or Dani Divine :-D
