Marine Pop

The Marine Pop was a submarine used only in World 2-3 in Super Mario Land. In this machine, Mario could travel through the water while shooting torpedoes to defeat the enemies. The machine could also be used to take out the boss of the level, Dragonzamasu. The player could either shoot at him until he is vanquished, or just go under him to find the switch to destroy him. Tamao is the only known creature who cannot be destroyed by the Marine Pop's torpedoes. The Marine Pop could also grow with Mario as he grabbed Mushrooms, and also could turn invincible with Stars. Even though it could power up with those, Flowers would not affect it.
