The Dephysicalise tool is a tool that originated from the LittleBigPlanet PS Vita title, and was brought to LittleBigPlanet 3. This tool is used to remove the physics from items - meaning they become un-collidable (the player and other objects can pass through them as if they are not present).

Careful use of this tool can be used to decrease huge amounts of lag and save space on the Thermometer.
