I know this will probably sound weird, but why is there no fan art of Spike and Daring Do as a couple, I haven't even seen fanfoals of the pairing. Heck, the only fanfic that focuses on them as a couple is this story that I started writing a few months ago

And yes, it is a clop story, but the clop only shows up in two chapters at the moment. Although, there is also quite a bit of suggestive material in it. If that's not your sort of thing, fine, but at the very least you should know there is one fan work that actually makes a go at setting the two up as a couple.
But seriously, I have found zero fanworks by other creators even pretending to explore this pairing, I'm a little disappointed in the fanbase over that.
