Play Nakayoshi Pet Series 3 - Kawaii Koinu (Japan) Online

Game Overview

Nakayoshi Pet Series 3 - Kawaii Koinu is one of those Game Boy Color games that just oozes charm. You start with this tiny, ridiculously cute pixel pup—like, the kind of dog that makes you go "aww" every time it tilts its head. The first thing you’ll do? Probably panic a little because you don’t want to mess up raising it, but don’t worry—this isn’t one of those punishing pet sims. Feed it, play fetch (with a little bone sprite, because of course), and watch it get all bouncy when it’s happy.

What I love is how uncomplicated it feels. The colors are bright in that classic GBC way, and the animations have this goofy energy—like when your pup spins in circles for no reason. It’s definitely more playful than some of the other Nakayoshi Pet games, leaning hard into the "kawaii" vibe. No deep stats to manage, just a happy little time-waster that’s perfect for short bursts. If you’ve ever missed the simplicity of old-school virtual pets, this one’s a winner.
