Super Mario World/Enemies/Ninji

While they do not appear at the credits screen, there are actually Ninjis in this game. Ninjies are star-shaped, creatures that just jump around, trying to bump into Mario or Luigi to hurt them. They are often found alongside Mechakoopas. Ninjis originally appeared in Super Mario Bros. 2.

Unlike Super Mario Bros. 2, the Ninji of Super Mario World appears black even in the dark, thus making them nearly invisible unless a searchlight is switched on. Simply jumping on Ninji will defeat them (unlike in Super Mario Bros. 2, where the main way to defeat an enemy is by throwing another enemy or object at them).
