A flying mint bunny has also been spotted with the character England in the anime/webcomic Hetalia. This is simply further proof of their existence.
"It was strange because the flying mint bunny was the first thing I saw when I woke from the coma."
"I'll be right back. I have to put my flying mint bunny outside. It's too cheerful sometimes, to the point where it can be irritating."
"Flying mint bunny and I have been united since that day I became addicted to cocaine. What a wonderful day."
