"Top partners" (such as the SUSY stop) are essential components of most mechanisms for solving the electroweak hierarchy problem, and therefore a central target of LHC searches. I will point out the loophole in arguments suggesting such partners should always be colored (and therefore easily produced). I then review the Twin Higgs mechanism for solving the little hierarchy problem with a dark (standard model neutral) sector, including an uncolored top partner, coupled to the standard model via the Higgs portal. After developing the minimal bottom-up model of this type I will describe its novel phenomenology in terms of displaced vertex decays of the Higgs boson.
