Play Teddy Boy Blues (Japan) (Proto) (Ep-MyCard) Online
You control a tiny armed teddy bear blasting through pastel nightmares—floating heads, mutant toys, and glitchy prototype weirdness that somehow works.

Game Overview
Teddy Boy Blues is one of those weird little Master System games that makes you go, "Wait, this was actually released?" You play as a teddy bear—tiny, armed, and surprisingly lethal—shooting your way through what feels like a toddler’s fever dream. The colors are soft pinks and blues, but the enemies? Giant floating heads, bouncing blobs, things that look like they escaped from a toy factory gone wrong.
It’s janky in that way only prototype games can be—sometimes your shots don’t land right, the scrolling’s a bit choppy—but that almost adds to the charm. There’s something hypnotic about how strange it all is. You’ll die a lot at first, mostly because half the enemies move in patterns that make zero sense, but once it clicks, you’ll keep going just to see what bizarre thing pops up next.
If you’ve ever wondered what a 1980s arcade shooter would look like if it was designed by someone who only had stuffed animals and candy as reference material, here’s your answer.
