Boomsday Machine

Bowser Jr.'s Boomsday Machine is a castle-like boss who appears to be in the game Super Mario Galaxy 2.It is fought in Bowser Jr.'s Boom Bunker.Bowser Jr.'s new ride is a fireball-spewing tower of death. There are ample Cloud Flowers around the area to grab. Note:the three updrafts that lead to clouds high above. Ascending these and using them to get to the top of the tower is what this battle is all about.For the first round,Mario must run for one of the updrafts, spin to create cloud and ride it to the Cloud Flower refill. From here you can long-jump to the top of the Boomsday Machine with the help of a few cloud platforms. Try to jump slightly diagonally so you avoid the cloud-zapping yellow projectiles.Once Mario reaches the top of the tower, ground-pound the glass. You need to do this two more times!The second round is much like the first, but now the tower will attempt to vacuum the area, pulling the clouds out from under your feet. Mario should still be able to just long-jump to the top of the tower in the same manner, just be ready to make a backup platform if Mario gets sucked up.Mario also need to watch out for an electric shield that covers Bowser Jr.'s dome periodically. You may have to use a cloud platform to wait this out before making your second attack.In the final round, the tower goes mobile. This makes your climb to the top more difficult, since Jr.'s dome is much higher up, but the moving tank doesn't present that much more of a threat. You still need to watch out for yellow projectiles, the spinning fire wheel and the vacuum attack, but you should really focus on climbing.

Once you reach the top of an updraft, you need to use the Cloud Flower refill to get to an even higher cloud tier. Use long jumps to get to the distant cloud and you can score another refill. From here you can reach the brittle dome with your cloud platform recharge. Ground-pound the glass dome a third time to take Bowser Jr. out.
