Query: Potent off-gasing!!!

OK, so any Buzz Lightyear costume HAS TO HAVE THIS!! Very cute! But get your gas masks ready and some advil. This thing stinks like nothing I've smelled before. I received this today and immediately took it out of the package to air out. I've worked with industrial plastics and this should require PPE and OASHA air quality testing. It sat opened and unfolded (but not yet inflated) for 4 hours. TO air out, because I know these things can have an odor. Its now been inflated for an hour and MY WHOLE HOUSE SMELLS LIKE VINYL!!! I am not kidding. My head is pounding and I think I have the munchies.We have a Halloween Party to go to on Friday night. Today is Monday, if I do not deem this safe for my 3 year old by then it will go into the trash.But it is holding air and is super cute. Will update this review again if it gets worn.
