I tempted Starboy into a bath he didn't want to take with some shaving cream paint. (Thank you, Internet!) It's just shaving cream and food coloring. He also used a paintbrush for a while.
He really went to town with it. More disgusting than that fake-melted-ice-cream water was the perfumed smell of the shaving cream. Jesus. I recommend you find scent-free shaving cream for stuff like this. He went to bed smelling like a 14-year-old.
