Bubbly Clouds is the third stage in Kirby Fighters and the seventh stage in Kirby Fighters Deluxe. Based on the stage the same name which appears in Spring Breeze, this arena takes place in the area where Kirby fights Kracko.
Bubbly Clouds features two platforms, with each one attached to an arch in the mid-ground. The main hazard of the stage is Kracko himself, who will enter the battle and do one of his attacks: get close to some of the Kirby's and use his revolution beam attack, hover above someone and pour down rain, or move from one side of the arena to the other while dropping lightning that can only be avoided by dodging or standing under the platforms. Kracko cannot be defeated, unlike Lololo & Lalala during their appearance in the Castle Lololo stage.
In Kirby Fighters, the fighting is in the daytime, similarly to most of Bubbly Clouds. In Kirby Fighters Deluxe, the fighting takes place at nighttime, as it did when fighting Kracko in Kirby Super Star/Ultra. This is more likely to be the fourth stage in Kirby Fighters Deluxe's single-player, and is always the stage the player fights Kracko in during round 5 (albeit without the additional platforms). The music that plays here is the boss battle theme in Kirby Super Star and Kirby Super Star Ultra. When fighting against Kracko in Kirby Fighters Deluxe's singe-player, the music that plays is the Kirby Fighters theme.
- If playing Kirby Fighters Deluxe's single-player on Very Hard difficulty, during the fight with Kracko, the ground is changed to spell out HAL in lavender and beige tiles, in addition to yellow and green tiles. This is made more noticeable after Kracko is defeated.
