Nokobon

From the Super Mario Wiki

A Nokobon is a black Koopa-like creature found in the game Super Mario Land. Nokobons explode shortly after being stomped and are immune to superballs. They have bombs as shells, implying that they may be related to Bob-ombs. Luckily, the blast radius was not very large. They replace Koopa Troopas in Super Mario Land, as it would've taken longer to program the richochet effects of Koopa shells on the Game Boy.

Nokobons are the most common enemy in the game, appearing in all levels except for 2-3 and the last one. They move like Red Koopa Troopas as well. Nokobons resemble ordinary Koopa Troopas with a black shell. It is widely believed that the Black Shells from Mario Kart Arcade GP are in fact Nokobon shells.

A different type of possible Nokobon appears in Super Mario Land 2. In this game, they're called Noko Bombettes. If Nokobon's name was translated to English, it would roughly be translated as Turtle Robot. They are called Nokobons in the US due to poor localization, as Super Mario Land was rushed to the US to be sold with the Game Boy.^{[citation needed]}
