Boss Battles from the upcoming Wii U game New Super Mario Bros. 3.
Boss 1: Lemmy Koopa
Lemmy Koopa is (just like New Super Mario Bros. U) the boss of World 1. In the tower battle, it's just a simple room with two Koopa Paratroopas flying at each side. Lemmy shoots balls at Mario and Co. When he is stomped on twice, he will shoot two balls at the same time. The third defeats him and he jumps off to the castle.In his final battle in the castle, he will roll on his up walls and on the ceiling. This time, he shoots 2 yellow fireballs with his magic wand. He also throws Koopa Shells down and make green Koopa Troopas appear. Red ones come out of two warp pipes on the ceiling. Unlike in his other battles, he bumps into the walls as he's spinning in his shell. After, the first time he is stomped on, another warp pipe grows on the ceiling but he still shoots two fireballs and drop one shell. After the second stomp, he shoots 3 fireballs and throw 2 koopa shells down making it harder. After 3 stomps, he is defeated and the key lead to World 2.
Boss 2: Iggy Koopa
Iggy Koopa is the boss of World 2, just like in New Super Mario Bros. 2. In his tower, 4 Spike Tops are walking all over the stage room. Iggy shoots a fireball at Mario and then he does a cartwheel to the other side of the room. Stomping on him twice will cause him to jump and cartwheel to the other side of the room after shooting a fireball. After his third stomp, he falls to the ground and then jumps off to his castle.
In his castle battle, most of the room is flooded up with poisoned water. Iggy is able to swim in it. Mario can keep safe by staying on some path above the room but must avoid Sandfish (a new enemy in the game). Iggy will shoot 3 fireballs. When the poisoned water goes down, Mario can stomp on Iggy and use red moving platforms to get back to upper paths before the room gets flooded. After 2 stomps, he will try to splash poisoned water at Mario making it difficult. After a third stomp, Iggy is defeated and the key takes you to World 3.
