Androgynous Metalhead Tails

I've always wondered what made Tails so adorable. It's because depending on the art style, he looks both masculine and feminine at the same time, hence the title. I see it more clearly in traditional 2-D art styles as opposed to modern 3-D graphics. It might become more apparent if Sega and Sonic Team develop another 2-D entry, but that remains to be seen. That's the way I see it, anyway.
