The red power bricks an item that is in a different place for each and every person but if you know 1 location you have a 1/11% chance of it being the red power brick why? Well because there are 11 things in the map to be found and they are randomly placed somewhere even the red power brick. It could be anywhere with in the 11 locations. So the only way to get it is luck or knowing all the locations if you know 5 locations that's a 5/11% chance of getting the red power brick. Now I have all of the red power bricks besides the Cloud City Trap one and I also have every person and 93m studs if you notice this game looks like lego Indiana jones and mostly all the lego games but anyway on lego Indiana jones it's different in a way such as the was it looks speaking of lego Indiana jones I have every thing in the game(incluing 2billion studs) besides 2 of the statues I am at 98% done... Well anyway I'm sorry to disappoint you but red power brick locations are in a different place every time even if you start a new game.
