We've been through dozens of hygienic panties for female dogs in our time on this Earth, but we've yet to see one this special. According to the arse end of this particular pair, designed for the unspayed bitch in your life, they're compatible with Game Boy Colour. Handy, in the case of needing to play some Metal Gear Ghost Babel while taking Muffin for a walk during her time with "the curse". To be perfectly clear, the text does read that the pantsu are "atible with AMEBOY COLOR" so don't toss your legacy handhelds out just yet.
To answer your question, Adam, we have absolutely no idea WTF this is all about. Theories are certainly welcome.
