Bombshell Koopa

Bombshell Koopas, originally known as Nokobon or Nobokon , are a black-shelled species of Koopa Troopas found in the game Super Mario Land. Bombshell Koopas are not immune to Superballs, and they explode shortly after being stomped (although the blast radius is not very large), making them similar to Bob-ombs.

Bombshell Koopas are the most common enemy in Super Mario Land, appearing in all levels except for Worlds 2-3 (the underwater level) and 4-3 (the flying level). Like red-shelled Koopa Troopas, Bombshell Koopas do not walk off edges, but merely pace back and forth on the platform.

In Super Mario Land 2: 6 Golden Coins, normal Koopa Troopas appear as enemies, and while a new Buzzy Beetle-like enemy fills the exploding-shell niche, their name, Noko Bombette, is a reference to their "Nokobon" predecessor. (Bombshell Koopas were only referred to as such in the 2011 port of Super Mario Land to the Virtual Console, almost twenty years after Super Mario Land 2: 6 Golden Coins was released.)

In WarioWare Gold, a Bombshell Koopa appears in the second level of the microgame Super Mario Land.
