Since an English name's been found, one of the examples on MarioWiki:Naming needs to be modified.
"Kurosu" has an English name in the form of Bird (Super Mario Land 2: 6 Golden Coins), so using that doesn't quite work out.
If there is no official English name, then the first international name from a non-English region is used. For example, the giant bird boss from Super Mario Land 2: 6 Golden Coins does not have an official English name. However, the official German and Japanese names are known as "Radonkel" and "Kurosu" respectively. As the Japanese release came before the German release, the Japanese name "Kurosu" gets the article title. However, if an official English name is found, then it becomes the article's title.
