Alphys is cute and cuddly to begin with. Makes sense she'd get even more cuddly when you fill her up like this...

The next phase will be Undyne fattening Alphys up with her own infinite ice cream machine while tenderly rubbing her belly! Mettaton could massage her back and shoulders. Think of it as "spa therapy" for her anxiety. ^W^
