Burning Wax is a sequel to Melted Plastic but not reflecting on one person. Cry Baby is now talking about everyone plastic in her life/town. In the Mad Hatter MV you can see burning wax.
Sick of "perfects"
Sick of the plastics
It's time to burn them
Burn them down
Oh, I am sick of being the odd one out
Being me is what I'm about
All of you are bunch of fucking wax humans
It's time to burn you wax humans down
Wax humans down
Time to make burning wax
