A Bubble is an item found in Kirby: Squeak Squad. It is meant to contain other items, and can usually be found floating about in various areas of the game. Kirby can Inhale it to store the bubble, and its item, in the Copy Palette for later use. If Kirby does not wish to keep the bubble in his stomach, he can spit it back out, and it will return to the stage as a bubble.
Bubbles can contain one of the following: Food items, Copy Abilities, mini Kirby icons, 1-Ups, spitting Stars, or nothing at all. Additionally, when inside the Copy Palette, some of them can be combined with each-other to create new em-bubbled items. For instance, combining two Ability Bubbles with each-other can create a random new ability, or, depending on the components, a specific combo, like Fire Sword.
Using the Bubble ability, Kirby can create his own bubble containers by blowing them at enemies. This turns them into bubbles containing Copy Abilities appropriate to the enemy, or a spitting star Bubble if the enemy had no ability.
