I was looking through the
List of Undumped Games on the wiki, and one particular game caught my eye: a little-known Korean Famicom game by Zemina called
Magic Kid Googoo.
Y'all may notice something vaguely familiar about the screenshots here, but... I'll get to that in a bit.
A Korean gamer posted a video and some screenshots of the game:

Koo Eun-joong, the lead developer of this game, was also lead developer on Buzz & Waldog. Even the music has the same composer, Kwon Dae-yong.
Now you see the similarities, right?
Edit: I'd read about this, but totally forgotten it till now-- Open, the developer of Buzz & Waldog, was founded by a bunch of former Zemina developers. So yep, this is definitely the team that split off to become Open.
