I thought it was very romantic.
[edit] In the poor girl's defence, some points;
It's not like Rapple thinks Bugbears are innately hideous. Why, his most treasured (and secret) possession is a little Bugbear plushie!
As I see it, Rapple has just been married to an
amazonian warrior princess. The noteworthy features of a bugbear are that they have claws and faintly bearlike noses, and swept-back ears. Really, they are just tall, strong and rowdy (hob)goblins.
Now, I have some images. Technically, this isn't 100% accurate to the looks of a DnD Bugbear, but these images, I believe, are quite a fair representation from the goblinoid perspective.
Maybe these will take some of the sting out of the situation? More-or-less Safe For Work. I believe the Bugbear in question is a fertility-priestess. More images exist, and of similar by the same artist. None are remotely SFW, though.
