Whinnie was a male rabbit that Melanie Martinez used to have. He was decapitated after Melanie gave him away to her friend, later causing her to get a tattoo of him.
Melanie shared with Fuse the story, "It was actually my first pet ever. And then I got a dog and my parents told me I couldn’t have a bunny and a dog, so we all decided to give the bunny away to a friend of a friend who already had a bunny. So we thought 'It’ll have a friend, that’s amazing, that’s awesome.' So they left my bunny and their bunny in the backyard unattended for like, four hours. They ended up finding their bunny in their neighbor’s backyard and my bunny’s head was in their yard."
- Whinnie appears in the Dollhouse music video. Melanie stated that there wasn't a particular reason to include him other than he wanted to be on camera. 
- According to an old tweet that was later deleted, Melanie dyed Whinnie multiple colours.
