To promote the horror Annabelle: Creation, Korean Snapchat clone SNOW has launched a camera mask which enables users to “transform” into demonic doll. (By the way, did you stay for the post-credits stinger?)
It's actually pretty easy. Of course, you need the SNOW app on your Android or iPhone first.
Step 1: Open Snow app.
Step 2: Tap the smiley face icon for Masks selection.
Step 3: Tap on NEW icon and tap on ANNABELLE thumbnail.
Step 4: Scare the living daylights out of your online enemies.
