Lydia is an alien from the planet Glitterius. Her 5 year mission - to convert as many people to stamping as possible before she beams all of us up to her spaceship. Then she will take us all back to Glitterius where untold riches will be bestowed upon us. In return, we are forced to stamp every day and send all of our creations to the Big Head.
