Here's a nice aqua blue tee with just Tails. It's slightly unusual because the cut/style is called "BabyDoll" & is usually for girls. (though in adult sizes it may fit anyone) It has right-out-of-Sonic2 pixelated Tails & zone background for a nostalgic look. Having the graphic be a circle is also interesting.
