This achievement is unlocked once you save your cousin from the cell he was in (after you get the translocator mcguffin) there is a room to the left of a new area that the new gun gets you to, once in the area you must use the red gun to shoot through the lava fall in the room (which is turned on using a green switch in the corner, triggered by the translocator ball) and shoot the gun through the lava fall and hit the cardboard on both sides of the room, in the room on the right there are the purple bugs that like to eat carrots, use the line from the purple gun to lead the flies through the lava making them fire flies and lead them to the cardboard on the left side and it will burn, then the achievement will pop.
