Seems like she ate something from the Wonka factory, or maybe Pepper Clark gave her a spiked treat.
She doesn't seem to mind however, but we should probably get that juice out of her fast. (I DON'T to popping/bursting/exploding BTW. Just not comfy with that.) Who knows, afterwards, she might become super-elastic like DC Universe's Plastic Man or Stretch-O-Mutt.
& I've been meaning to do more blueberry inflation art anyways, so here ya go. Enjoy!
