Super Mario 3D World: Castle-Castle -- Bowser's Lavalake Keep

It's time to finally take on Bowser! You'll need 130 Green Stars to unlock the level. To get all of the items, I recommend bringing in a Cat Suit. There are Boomerang Bros and Podoboos here. Stomp the Boomerang Bro near the first Green Star for a Boomerang Flower. You'll need to switch between the two to get the Green Stars and stamp. The first Green Star is low over the lava between two walls. Slide down, then wall jump or climb to safety. To the right is a soccer bomb blaster and some gray bricks. Behind the blaster is a grate with the second Green Star on top. Climb using the Cat Suit to get it. Go back down and use a soccer bomb to destroy the gray bricks. Wall jump up or climb in the area where the gray bricks were for the stamp. Step on the P-Switch at the bottom to lower the grate so you can walk on it. Up ahead are square spike bars and Fire Bros. It's easy to get rid of them with the boomerang. Up ahead are more soccer bomb blasters and the midpoint.

There's a long, narrow pathway ahead where many Podoboos will appear. Run quickly to avoid being burned. The third Green Star is over the lava. Use the boomerang to get it. If you need an extra powerup, there's a Boomerang Flower past the second set of Podoboos, in an invisible block over a metal plate. Keep the Cat Suit if you can. Up ahead are the square spike bars and Hammer Bros. Defeat the Hammer Bros. to make a path appear to the warp box.

The warp box leads to some stairs. At the top of the stairs, Bowser appears in his car again. It's the same battle as before, with spikes and lava pillars. At points, the road will split so there is no middle part of the road. Bowser also breathes fire more often. Switch to the Cat Suit to make the soccer bombs do more damage to Bowser's car. Once he is defeated, the bridge falls and Bowser falls into the lava. A fanfare plays and the warp box to the flagpole appears.

The red Sprixie Princess is trapped at the flagpole with the other six flying around her. Break the jar and all of them dance. Bowser reappears, grabs them, and stuffs them into one large jar. He leaves, the jar smashes, and a beam of light appears from below. Outside the castle is a sparkling clear pipe.

The stamp is of Boomerang Mario.
