Bubbles are objects that can be found in certain Kirby games that can contain items and objects which, depending on what's inside, may help or hinder Kirby on his adventures. Bubbles have varying properties depending on what game they appear in, but generally speaking, they are large floating objects that can be interacted with, popped, or collected and usually contain something, whether that be a Copy Essence, a food item, or even a bomb. Some enemies such as Crabbo, Buboo, and Moggy are also capable of generating (or are partially made of) bubbles. When using the Bubble Copy Ability, Kirby himself can create bubbles out of the enemies he defeats.
Kirby: Squeak Squad
Bubbles make their first appearance as substantial objects in Kirby: Squeak Squad, where lots of items can be found contained inside them. Despite what may be expected, these bubbles cannot be popped by Kirby himself, and instead must be interacted with by having Kirby touch or inhale them, which will transfer the bubble and its item into Kirby's Copy Palette. From there, they can be interacted with using the Nintendo DS stylus in various ways. Touching a bubbled object when Kirby's Copy Palette is already full will instead merely cause the bubble to be pushed away. For more information about what items can appear in bubbles and how they can be used, see the Copy Palette page.
When Kirby has the Bubble Copy Ability, he can transform enemies into bubbles containing Copy Abilities appropriate to that enemy's ability, or Star Bullets if that enemy was ability-neutral. This can also be done when possessing Bubble Head using Ghost Kirby.
Kirby Mass Attack
Bubbles return in Kirby Mass Attack, though in a more limited capacity. Here, they can be seen floating through the air in various stages, and often contain fruit or bombs. When a Kirby touches a bubble, he can drag it down and pop it to get the item inside. Enemies such as Moggy are also mostly composed of bubbles. In addition, bubbles containing air can be found in underwater stages, which the Kirbys can grab to prevent from drowning.
In addition to standard items, bubbles may also contain hints (depicted as a big question mark inside the bubble). There are also Rainbow Bubbles at the end of various stages which, when popped, allows the Kirbys to progress into the next ring on the level map.
Kirby and the Rainbow Curse
In Kirby and the Rainbow Curse, certain enemies such as Crabbo will deploy bombs encased in bubbles that will slowly drift in a given direction. These can be popped using a rainbow rope, though it will destroy the rope in the process. Such bubbled bombs are also encountered on their own in Challenge Mode and when battling Claycia in The Final Battle. Bubbles can also contain Point Stars, which will drop when the bubble is popped.

During the battle with Claycia in Kirby and the Rainbow Curse, Kirby may have to deal with cannons that shoot bubbled bombs.
