There are several options open to you to resolve this.....
You could offer Hubby some house keeping money and tell him he's such a dear he deserves a night down the pub

......leaving you free to sort out the package.
With regard to the package itself I would suggest that whilst you are attempting to open it you take a small skewer and made some small air holes around the mouth/nose area.
Can you lift the pacakage? If so try to get it into the bath/shower and let the wrapping soak off.........but remember to support the head part out of the water
Failing that bring a bucket of water to the package and care fully soak areas if you do legs and arms fisrt you may find that the package is then able to assist itself.
It is said that desperate needs call for desperate measures and if you are still stuggling you could try burning small areas........you should do this with a lighter and have plenty of water handy!!!

If you can burn a small hole in a cavity area

or were packaging is looser you will then be able to rip the rest apart
Hope this helps
