Bubbles are recurring obstacles in the Chicken Invaders franchise, used since Ultimate Omelette. They protect enemies and items that are inside of them from regular Weapons (Missiles and certain Satellites may still hurt them), and they are invulnerable. The only way to get rid of them, in case they don't pop in and out, is by killing non-bubbled enemies near them.
Bubbles in this game are used by Chickens in Wave 57, 114, and 101. The Bubbles in Wave 57 have to be destroyed by killing the unbubbled Chicks/Chickens near them, while the ones in Wave 101 and 114 will pop in and out. You will have to damage the Chickens that are protected by them while the Bubbles are not there. The Bubbles in this game are more often used by the Space Burger Corporation to protect their Food convoys in Waves 91, 92, 94, 96, 97, and 98. In those waves, the Space Burger Droids that lead the convoys have to be destroyed for the food to be freed. They are in total used in nine waves. They are invulnerable to regular weapons and the Microgun and they give no points once they pop.
Cluck of the Dark Side[]
Bubbles in this game are used solely by Chickens. They see much, much less use, as they only appear once, in Wave 68. Bubbles in this wave will have to be destroyed by killing the unbubbled enemies. This time around, the Bubbles don't contain any items, only enemies. Just like in the previous game, they are invulnerable to regular weapons and the Microgun and they give no points once they pop.
