Big Bird cannot remember how to write a lowercase "r". Luckily, a cute letter "r" drops onto his easel! Big Bird decides they will be friends after "r" kisses his beak! Little "r" does tricks, like roll over. "R" is so terrific, Big Bird draws its picture. When Big Bird wants to introduce "r" to Mr. Hooper and Gordon, little "r" has disappeared. They do not believe Big Bird and think he is imagining it. Alone again, Big Bird calls for little "r", who bounces back, this time with an uppercase "R"! Big Bird gets to practice drawing uppercase "R" now. After he draws a big "R", the letters bounce away. Mr. Hooper and Gordon visit Big Bird and do not believe two letter Rs exist. Luckily, big and little "r" bounce back. The adults realize the Rs do exist and not only in Big Bird's imagination! (thetvdb.com)
