Counting: BJ and Riff find a pirate map, but in order to find the treasure, they have to be able to count. Since Baby Bop hasn't learned to count yet, Barney offers to help teach her so she is not left behind. In the end, Baby Bop learns to count and realizes that feeling good about herself is the greatest treasure in the world! Letters: It's time for a music concert in the park. As Riff works on his "one-man band", the others make posters for the show. Everyone enjoys Riff's calypso rendition of a favorite song, and they all enjoy helping each other!
