Play Nintama Rantarou - Ninjutsu Gakuen ni Nyuugaku Shiyou no Dan (Japan) Online
Dodge teachers in pajamas, flub ninja tricks, and sneak around a school where the mini-games feel like pranks—this one’s got that same goofy charm as the anime.

Game Overview
Ever wanted to go to ninja school, but like... the fun kind where you're more likely to trip over your own sandals than actually master any techniques? That's Nintama Rantarou in a nutshell. It's based on that old anime where ninja trainees spend more time goofing off than training, and the Game Boy Color version nails that vibe perfectly.
You'll sneak around the academy avoiding teachers (who somehow never notice the kid-shaped lumps under blankets), solve weird little puzzles, and play mini-games that feel like they were designed by the class clown. The pixel art's surprisingly lively—Rantarou's dopey grin when he messes up is weirdly endearing. It's not hard, but that's the point; failing is half the fun here.
Honestly, it's one of those games that makes you smile just by existing. If you grew up with the anime or just love quirky retro stuff, this little cart's worth digging up.
