I wonder if it could have anything to do with those new Halloween Design Sally Hansen Salon Effects I found in that abandoned, probably haunted, mansion I visited last night? Oh, wait! I got them at the well-lit, totally not creepy, drug store.
p.s. This design is called “Ghoulie Girl”, there are four others available. Be warned, the designs are quickly selling out so hurry up and scare up a box of your own!
