From the Shirtpunch.com's interview with the artist:
"Question: What inspired this design?
Answer: I miss the Capn's villains, the Soggies. So I wanted to remember them by killing off their arch enemy. It's sad that almost all of the cereal villains are gone. All we're left with are the kids that won't share their sugar cereal with a rabbit."
