Fire is a form of danger. When a players Sackboy makes contact with a flaming object, they will be burned to death. A Sackperson can simply glance off a flame if they JUST touch it.Flaming objects appear charred with orange wisps of flame curling around them. This hazard is most often found in The Savannah, The Islands, and The Temples. It takes 2 burns to kill a SackPerson. You can also use fire in your own levels. It is found under the "tools bag". In the second game, the "Play with Fire" pin can be earned by touching fire WITHOUT losing a life.
In Little Big Planet 2 it is most commonly found in Eve's Asylum.
