The Tower here leads to a fight with Kamek, who previously in the game is only seen enhancing the Koopalings when the heroes reach them in Castles. This world also features the third and final fight with Bowser Jr., once again on an Airship. The final level here features the two-part battle with Bowser, who is not once seen in the game up until that point. The Enemy Course in the level are Podoboos between 8-3 & 8-Tower; on the bridge.

8-1
In World 8-1, Mario and Co. have to go through a volcanic area full of lava. Raining Debris fall from the sky, which are hard to dodge as there are rising lava spouts, which block the players temporarily from progressing further if they don't have the Propeller Suit, and a cloud of hot ashes that chases them from the left to the right. The hot ashes kills them instantly on contact so they have to hurry.

8-2
This level contains more falling debris and with spinning wheels on the ground. As soon as Mario and the co. enter the pipe, they end up underground filled with more lava. Goombas will appear many times on this stage. Including the spiked balls rolling around. The team will just have to dodge the obstacles and will get through. However there is a secret exit, after the Mario team passes a yellow and a red pipe, they will see more spiked balls rolling forward slowly. Right at the ledge if the team drops down and heads right to the wall a secret entrance will allow them to enter a pipe further if they keep heading right. Once gone into the pipe, the team will see that the ground is spinning very fast. They'll have to either keep jumping until the end. They must also watch out that Goombas can appear on the spinning ground. Once they get through, they'll open up the secret exit to 8-7.

8-3
This level starts out with huge lava waves, if Mario and Co. aren't careful and land in the lava they instantly lose a life. It contains mostly platforms that sink into the lava, but rises back up if jumped off. If Mario and Co. are patient and are careful they can get through easily.

Enemy Course

8-7
The level is secret, in which can only be unlocked by taking the secret path on World 8-2. This is the first and only level were you see the Bonecoasters. There are a total of five coaster throughout the level (two at the underground section, three at the above ground section). The bonecoaster helps the four dodge the lava geysers that are constantly shooting from the lava. The first Star Coin is located on the second bonecoaster, were it is barely above the lava, which Mario, Luigi, Blue Toad, or Yellow Toad must grab as the bonecoaster comes out of the lava. The second star coin is located above two lava gysers, which the four must jump off the third bonecoaster to grab it. The last star coin is found between the four and fifth bonecoaster. Mario and co. must stay on the fourth bonecoaster, grab the coin, and jump to the fifth bonecoaster before they touch the geyser. After the bonecoasters, it is a short jump onto the flagpole, which leads Mario and friends to 8-Airship.

8-Ship
The last airship level in the game. The main enemy in the course is the Mecha-Koopa, but the biggest danger is the level is the cannons and you have to dodge a barrage of cannonballs at one point. At the end is the last battle against Bowser Jr.
