In the 1990s, Mattel's trademark on the "Sizzlers" name had lapsed and toy company Playing Mantis released a line new Sizzlers line in NASCAR stock car models and copied the "Fat Track" as the ""Stocker 400"" and ""Mach 500"" track sets to capitalize on the booming popularity of NASCAR in that decade. The "Juice Machine" was renamed the ""Mega-Charger"" and incorporated a more efficient "trickle charge" rather than the "dump charge" of the original machines. Interest in the toys began to increase once again. They were taken off the market after Mattel filed a lawsuit against Playing Mantis. However, "Sizzlers" returned again in 2006, when Mattel struck an exclusive deal with Target stores to re-release "Sizzlers" cars, the ""Big O"" Fat track, Juice Machine and car carrying case—all in the original packaging from the 1970s. As of January 2009, the Sizzlers line has been discontinued by Target.
