Polly Pocket dolls were originally called that because the doll was less than an inch high and the whole play-set closed in on itself and fit easily into your pocket. This has not been referenced in years, as Polly has grown to be much taller and her play-sets expansive.
Hot Wheels introduced a car called "Purple Passion" in the early '90s. It was a 40s style hot rod painted purple. The car has been reissued several times since then, but not always in purple.
