George Sr. and Barbara punish the Lil' Gang for destroying the White House by sending them to New Orleans to help with the rebuilding effort after Hurricane Katrina. They end up creating a suprise Mardi Gras float (out of a tank that was supposed to be a FEMA trailer and money that was being kept from the residents) trying to cheer up the residents. They instead crash into one of the levees and flood the city. Meanwhile George Sr. and Barbara cannot pay of the mortgages for the White House and look to sell it, with many of the Lil' Politicians looking to buy it. They eventually pay it off with all the money on the Mardi Gras float.
