Over-inflated?

Had a short trip to Liverpool to catch Chagall at the Tate. Walking back to Lime St, my eye was caught by this gang of young women who I guessed were returning from a spree, judging by the large pile of bags beside them. One appeared to have acquired an inflatable friend. I didn't ask what she planned to do with it (a) because she had difficulty in understanding my simple request to take the photo, which had to be translated by the woman standing and (b) in any case it might have seemed rude.

I hope they're very happy together.
