I'm looking for a Cookie Run Kingdom fic where Shadow Milk Cookie shapeshifts into a rabbit so he can spy on Pure Vanilla Cookie. I found this story on AO3 but clicked on a link in the fic to read a similar story called "Bluebell". (I think Bluebell inspired the one I'm currently looking for?) After I was done reading Bluebell I couldn't find the fic that I was originally on. I think the fic might have been called, "Leporidae" or something like that. But I'm not quite sure.

So, uh, remember this post? https://www.reddit.com/r/ShadowVanilla/comments/1ua1vjj/deceitful_daydream_concept_idea_because_i_finally/

Well, it's a fanfic now! (Tagged explicit, but it's 95% plot focused rather than smut) Go! Go read it! (If you're interested) https://archiveofourown.org/works/87276486/chapters/231169821
