Enchanted!arthur / rabbit!arthur

[xeohe]

Buried under my bookmarks is a fic somewhere where Arthur got turned into a rabbit that Merlin adopted (and named Penn, I think, and he doesn't know it's Arthur). It's also a magic reveal fic because he does magic in front of rabbit!Arthur. Arthur turns back into a human every morning, I think. Also features a pining!Merlin who lets his woes out on rabbit!Arthur. Help, please!

FOUND! The Tale of the Teapot by Moorishflower. Thanks, justine_lark~!
