Kamikaze Koopa

Kamikaze Koopas are enemies that only appear in Super Mario World and it's remake.

Appearance
Kamikaze Koopas in Super Mario World are created when a Yellow Beach Koopa enters a shell of any color. Kamikaze Koopas are almost invincible and can't be defeated by jumps. The shell also follows Mario or Luigi in an attempt to hit them. If Yoshi eats a Kamikaze Koopa's shell, he will gain all 3 abilities from Red Shells, Blue Shells and Yellow Shells, as long as Yoshi keeps the shell in his mouth. To defeat Kamikaze Koopas, the player must eat the shell with Yoshi, Spin Jump on the shell, or make contact with the shell with a Starman.
