5 minutes alone with...
Just in case you're wondering, I didn't freak out over his attempt to draw tiger stripes on his face. Stardust actually went to a party where they had face painting and he was trying to recreate the event. I took him to the mirror and showed him that if the ink doesn't come off then it will stain his face for a long time because marker pen ink is not always washable like face paint. Then I gave him a wet towel so that he could wipe it off himself. He was able to wipe it mostly clean, but he was not so successful with the stripes on his legs.
