Naruto: Ino-Pig (Patreon)

Ino and Sakura are ordered to go undercover at a pig farm in order to scout out the place not just for enemy ninjas, but to also obtain information they may be trading in secret. However, one wrong move causes Ino to blend in with the pigs, losing her identity except for Sakura, who can see through her disguise. Even worse, the pigs seem especially interested in mating with her perceived pig state.
