I’m having trouble finding a repetitive japanese song.

So there's this very silly, repetitive and elementary japanese song sung by a male. The song is relatively old and pretty popular iirc.

Now it gets very blurry. I think the song made references to the sky (stuff like being a star??) or maybe about some animals, like cows or dogs?? I think the music video was the singer doing a simple dance, maybe with a greenscreen.

I came across this song on this subreddit, after I made a post asking "why are japanese songs so deep and have such complex lyrics", where a user linked this song saying that not all japanese songs are deep, and in fact the one he linked was very simple.

So all I know for sure is that it was sung by a male and it had veryy simple lyrics. Does anyone here have any idea what I'm talking about?
