This cute little guy is from the original Super Mario Bros. His name is Goomba in English and Kuribō in Japanese.
The game takes place in a mushroom kingdom, so he was modeled after Shiitakes. But one developer thought he resembled a chestnut, and called him Kuribō. This means “chestnut boy” in Japanese.
There’s more to the story, but that’s the gist of his name duality.
