Well, I don't have a picture, but my sister in law collects frogs. My brother bought her a stuffed frog that is holding a valentine heart. It's adorable. Valentine's Day is a day for love, so what ever your mate fancies, would make the perfect gift. I have seen valentines pigs, Elvis valentines, penguins and now a frog.
How about a digitally remastered zebra?
Dragonfly "Heart" I don't own the image. It's a biology-type illustration of dragonflies.
I wouldn't call it romantic...come one, a pig.
