I think it's because of the very energetic and expressive animation for the anime but there is something very special about Oricorio. They just seem so high energy and don't seem like they have a care in the world. I just want to hug one so bad. I only watch the Sun and Moon anime just to see if Oricorio is in it. My favorite form is Pom Pom. It might be all the screen time it gets but they animate it so well. It's a shame they don't show it more. It doesn't have to fight or anything, it just has to be itself. It's also a shame we didn't get a new Oricorio form. It's always about the Eeveelutions and some new legendary Pokemon no one cares about. I feel it's a huge missed opportunity to not give it one.
