Sue is not happy being a kangaroo. Her relatives hop all around, and she gets an incredible migraine, among other pains. So she wanders away, looking for something new. She attempts to hang from a branch like a koala, but ends up in a heap on the ground! She then eyes a platypus basking in the sun, and imagines a life on the beach...but ends up in the hospital! At last Sue meets up with a wallaby, a miniature version of herself, and joins "in the throng,/Flouncing and jouncing and bouncing along." At last, she realizes that being a kangaroo suits her fine!!
