Vote for the Tupperware Party?

The Tupperware post obviously struck a chord with a number of people! Further research leads me to believe that Pattertwig The Squirrel [Prince Caspian]is possibly using Tupperware for storing nuts - but that his little rodent teeth damage the lids when he tries to 'burp the seal'- hence his need to purloin other peoples' lids.
Burp The Seal is not as far as I know, a character in any of the CSLewis Books!
