Boss Blitz

Boss Blitz, or , is the final course of World Flower in Super Mario 3D World. The stage consists of boss battle rematches with King Ka-Thunk, Pom Pom, King and Queen Hisstocrat, Boss Brolder, Boom Boom, and Motley Bossblob. It is unlocked via completion of Spiky Spike Bridge Sneak.

Layout
The course begins on a grassy platform with five Warp Boxes and one locked Warp Box. Each Warp Box leads to a boss fight, with a Key Coin awarded if the bosses are defeated. The bottom left box leads to King Ka-Thunk, the top left leads to Pom Pom, the top right leads to Boss Brolder, the bottom right leads to Boom Boom, and the center box leads to Hisstocrat and Queen Hisstocrat. All boss battles are fought in the same manner as they originally are, with the exception of King and Queen Hisstocrat, as they are fought at the same time. After all the Key Coins are collected, the unlocked Warp Box leads to a boss fight with Motley Bossblob. Upon his defeat, a Warp Box appears, leading to the Goal Pole.

Because the players are only given 500 seconds to defeat all the bosses, this course can be very difficult to complete if the players can't defeat each boss very quickly.
