The 2016 Treasure Hunts Series is part of the 2016 Hot Wheels line. Starting in 2013, Mattel has incorporated Treasure Hunts into other series instead of being their own series. Treasure Hunts are distinguished by the 'circle flame' symbol. In 2015, Mattel released a series of Super Treasure.. The 2016 super set includes premium vehicles that are hidden within other series like HW Green Speed. These Super Treasure Hunts are found by looking for Spectraflame paint, Real Rider wheels, and a "TH" graphic.
