They say they always know you're up to something when the house goes quiet... Exploring his mother's bedroom, a little boy discovers THE LIPSTICK. It begins on his lips, where it looks very good - MWAH! But then it goes for a little walk ...

squiggle, squiggle ... on the mirror ... scribble scribble ...

on the shiny floorboards ... smudge smudge. And even on the fluffy cat.

Uh-oh! What will happen when Mum, Dad and big sister see all this mess?
