Stage 10 (Kirby's Block Ball)

Brobo's stage is the second floating island of Blockworld and serves as the second level in Kirby's Block Ball. It is a mass of large gears. It is preceded by Kracko's stage and succeeded by King Dedede's Castle.

The stage opens with the following animation: Two Waddle Dees walk back and forth near a group of white and gray blocks. The ball defeats both of them, causing them to drop Flip items. The ball collects both, causing the blocks' colors to switch and then switch back. Two Kirbys fall down, pull out top hats and Star Rods, and pose.

Brobo's stage has a border line of 120,000.

Area 1
The area has a spiky floor and walls but a smooth ceiling. The player can control four paddles, at the top, bottom, and sides of the screen. The area is filled with four big, white square blocks; 16 white rectangular blocks; 19 Power Blocks; and 16 Ability Blocks. The Power Blocks surround the more vulnerable blocks, so the player must use the Kirby Power Bounce to destroy them. A Booler and a Propeller are stationed inside the box, the latter of which is protected by Ability Blocks. It drops a Changer item when defeated, allowing the player to choose a Copy Ability for Kirby.

Hidden objects: A Warp Star is hidden in the rightmost pocket of Ability Blocks.

Area 2
The area has a spiky floor, ceiling, and walls. The player can control four paddles, at the top, bottom, and sides of the screen. The area is filled with ten white rectangular blocks, eight gray rectangular blocks, two gray square blocks, three Power Blocks, 18 Ability Blocks, and an indestructible Metal Block. A Switch Block is located near the center of the area; it converts most of the blocks into Through Blocks, which grant Kirby a bonus if he clears them all under the time limit. A Bouncy and two Mumbies appear on the block formation; they drop a Changer and Flip items, respectively, the latter of which could double the number of hits required to clear the area.

Hidden objects: A Score Block is hidden in the leftmost pocket of Ability Blocks.

Area 3
The area has a spiky floor but a smooth ceiling and walls. The player can control a paddle at the bottom of the screen. The area is filled with 21 Power Blocks and 14 Metal Blocks. They are arranged in a spiral formation, so the ball must travel through it to its center. A Bronto Burt patrols the bottom of the area while a Kookler dwells near the end of the spiral; it drops a Crash item when defeated, which, when obtained, melts the Metal Blocks. The end of the spiral holds a Switch Block.

Target Shooting Area
The area has a spiky floor and walls but a smooth ceiling. The player can control paddles at the bottom and sides of the screen. The area is filled with 28 Star Blocks, eight Power Blocks, and 14 gray square blocks. Brobo moves up and down in the upper-middle portion of the area; hitting it four times causes it to flee and a Warp Star to descend from the ceiling. Touching it takes Kirby to the boss.

Boss Area
Brobo, now donning a metal body, serves as the boss of the stage. It stands on a platform in the center of the area. It hops between platforms and launches its fists at whatever paddle it sets its sights on--the attack shrinks the paddle if it makes contact. The spikes on the walls and floor are covered by whatever Star Blocks the player collected in the Target Shooting Area.

Trivia

 * Aside from being sources of points, the Propeller in the first area and the Bouncy in the second are largely pointless. In order to access them, Kirby must break the Ability Blocks surrounding them with a Copy Ability, and he must bring the ability from another stage. The Changers the enemies drop do little good if the player entered the stage with whichever ability he/she prefers.
 * Brobo's stage is the only stage in Kirby's Block Ball to feature an original boss.
 * Additionally, Brobo's stage is the only one in which the boss and the enemy in the Target Shooting Area are the exact same character. They are not merely members of the same species, a boss with an underling, or different forms of a boss.
