Nokobons are another type of Koopa. But instead of having a shell, it has a bomb for a shell! These Koopas are found in Birabuto Bash, but are found in other levels such as Skyscraper Domain. All have the same attacks, which is if you stomp on one, its "shell" will flash a couple of times before exploding. You can pick it up, but if you see it about to flash, drop it before it goes off! They can be used to defeat enemies, which is a minor strategy. They originate from Super Mario Land.
