What's this?
You take a sponge
What's this?
Aaa!! I'm an alien!
What's this?
You wash your hair
What's this?
You're in a bath
What's this?
You close your eyes
What's this?
You open your eyes
What's this?
You wash your body
What's this?
You are all green
What's this?
It's just green paint in your shower gel
