There is a long tradition of Celebrities Doing the Local Weather, and, real talk, Katy Perry is just okay at it. She has a decent level of enthusiasm, a couple of cute town jokes, and she does manage to communicate the basic facts of the weather. (Such as: It is warm in Australia!) We'd give her a solid B+. But this koala! Who is this Surprise Koala? Tell us more about him or her! A+ to Surprise Koala, would do business again.
