Play Osawagase! Penguin Boy (Japan) Online
You're a tiny penguin causing chaos—tipping vases, dodging guards, and waddling away before anyone catches you. The pixel art's chunky and charming, with music that bounces along as you sneak.

Osawagase! Penguin Boy came out for the Game Boy in 1990, developed by Tonkin House. It was part of that early wave of portable games where simple concepts and clear goals ruled; you didn't need a complicated story, just a character and a place to cause a little mischief.
You control a small penguin who sneaks through a mansion, tipping over vases and avoiding guards. The goal is to cause as much trouble as possible without getting caught. Movement is screen by screen; you enter a room, create chaos, and exit before the guards close in. The challenge comes from timing your actions and learning guard patrol routes. It feels mischievous and light, like a small rebellion in pixel form.
