Lots of Letters is the twenty-third episode of Barney & Friends' 15th season.
Mario Cannoli wraps up a day of substitute teaching. While most of their classmates leave, Joey and Sophia help Mario clean up the letters he used to teach the class. They almost finish cleaning up when Mario remembers a game using the letter B, just like the one he left on the board. As the trio plays "The "B" Game," Fred and Kristy come in and join them. Once the song wraps up, Mario accidentally knocks his box of letters over and sends each letter flying through the classroom. Barney soon comes to life and Mario explains what's going on, but before he finishes, a gust of wind comes into the classroom and not only blows the letters around, but sends some of them flying out of the room. The group decides to search for each of the letters. Along the way, they sing songs and do activities related to the letters they find. From ice skating and dancing to making Alphabet Soup, Barney and his friends find fun ways to learn about letters as they discover them. Once all the letters are retrieved, Mario realizes he has to still clean up the classroom. Barney suggests that they use the Clean-Up Clock to make cleaning up a bit of a game. To wrap up the fun, Barney spells out some of his favorite words: I L-O-V-E Y-O-U!
