Not sure if anyone had found this yet, but I figured I'd share it anyhow. I did find this on the android version, so I can't confirm if this can be found on pc.
I've been exploring the different areas in the game to see if I could find anything hidden and I found a part of the player home from yukkuri breeding observation in heaven. To get to it, go to heaven and walk straight towards your car until you pass it and keep walking. The player home will come into view momentarily an is located slightly on your left.
Sadly, none of the fixtures in the home work, which was pretty disappointing since I miss the frying pan and microwave from ybo :(
