Maddie painstakingly lines up the duckies on the side of the tub, while Mark sings an obnoxious song about ducks quacking.
Soon, the wall of the shower is not a good enough canvas for her to express her creativeness. So she moves on to using Maddie as a canvas.
Surprisingly, Maddie allows Ruthie to use her as a creative outlet. Ruthie sticks letters and numbers all over Maddie's front and then Maddie will even let her put them on her back, until she gets distracted.
Ever since she learned to say the word "dog", everything about the dogs is a distraction. Above, she heard the dogs barking and insisted on getting out of the tub, I am assuming to go find the dogs. In the process, ending what could have been a breathtaking work of art that Ruthie had begun on her back. The world will never get to see it, all because the dogs barked.
