Bubble Machine

The Bubble Machine is a LittleBigPlanet™1, 2 and 3 item in your "Tools Bag" located in the Emitters category. It is used to reset your drowning timer if you are creating a new level with water. The Bubble Machine was introduced in the Water Update from LittleBigPlanet™. You can also use its input using switches or sensors to turn it off and on.

Tweak Menu
The Bubble Machine's Tweak Menu has no special tweaks at all, only the "Visible in Play Mode" option is present.
