It's kinda scribbly and old (2007), but this drawing has always been a favorite of mine. It stars Teagan Green, a tea-loving human that turns into a Red River Hog by drinking a special Halloween Edition of Liptongue's Tea. He/she shifts gradually with the more tea they drink, so they could sip tea all day and become a full feral hog, drink more tea, and begin to gradually shift to human again by the end of the night. He/she says they've forgotten whether they started as a human or a hog. lol
