Mecha Nokonoko

The Koopa Troopa Sub is a boss in the game Yoshi's Safari. It is the boss of level 11: Dark Sea. It is a very large Koopa Troopa-based submarine with a turret mounted on its back, the turret would rotate and had four guns manned by seemingly ordinary Koopa Troopas. After the upper turret was destroyed the sub would reveal more guns mounted under his pop-up shell. Firing into it's open mouth, would destroy the rest of it's weapons causing the submarine to sink into the Dark Sea.
