Poko-tachi no sensuikan

The Poko-tachi no sensuikan (ポコたちの潜水艦, Poko's submarine) is a submarine used by the small octopuses in Super Mario-kun.

While Mario and friends are exploring the Turtle Zone's shipwrecked submarine, Wario's spies, two small octopuses, are ordered to take him out. The two takes their octopus-shaped submarine and attacks the shipwreck. Carrot separates from Mario and Yokkī, ending up in the secret level. After she fixes the "W" blocks formation into an "M", the shipwrecked submarine gets fixed, and Mario not only has a weapon to use against the enemies, but the enemies inside the submarine are no longer under Wario's control and help him in the battle. Mario sends the Cheep Cheeps and Bullet Bills against the enemies, but he ends up without ammunition and allies after the Poko-tachi no sensuikan comes out victorious. Yokkī then hits the CLEAR Block, turning Mario into Bomb Mario and shoots him against the enemies, defeating them.
