My GF is a Cartoon

Your girlfriend, Mona, is a cartoon mouse! The laws of physics don't apply to her, and seemingly don't apply to you either as long as she's interacting with you. And todays the day you have to introduce her to your parents! Are your parents humans that don't get along with toons? Or are they toons that were hoping you'd aim for a more...refined partner? And what sort of hijinks will you get up to with Mona?
