A cute reminder that art is in the eye of the beholder. When a hippo is impressed by a mouse’s painting of the sea, he asks to have his own portrait painted.  After posing very carefully, he is very impressed with the mouse-sized paper that gets painted solid gray because that’s all of him that would fit on the paper.  When they swap roles, and the hippo paints a portrait of the mouse, it turns out like a tiny dot in the middle of the paper, with which mouse is delighted.
