Princess Butterfly Kiss

Princess Butterfly Kiss is Marshmallow's majestic pet unicorn. She was first seen at the end of Viral Vote. She was lying down with Marshmallow on top but is only a picture. She appeared in Best Fiends Forever in Marshmallow's photo that was burnt by Grapefruit, causing Marshmallow's rage and ended up destroying the kitchen and grapefruit.
