Wait, do you mean the bubble in the tutorial level? You break those in sequence: by doing a quick dive, then by kicking flying enemies, then killing both enemies with parry to remove the bubble to the exit. If there's a tooltip bug or any other usability error then details would be really helpful. Outside of tutorial you are free to approach the bubbles in any way you want outside of shooting and kicks.
If it was the tutorial then remember there's an actualy gameplay level.
And yeah, you can lose most of the body parts until you are a walking skeleton without a head.
