Frog is on his way to band practice, but he has a problem - how can he cross the muddy stream that blocks his path? Go and Stop have helped Arty cross it before, so they are confident that they can help Frog too. Listening to the Moving Crew, Frog leaps from stepping stone to stepping stone. He almost leaps onto the grass on the opposite bank when he realises that he'll land on a bunch of bugs. What can they do?

Go and Stop encounter a new friend - Again. He introduces himself by singing a song about the things he loves to do. As his name suggests, he likes to do things again and again and again, usually in exactly the same way! Again reveals how much fun it can be to do the same moves, follow the same dance patterns, and run in the same way to win a race. But Again also enjoys finding repeated patterns. Patterns of shells, patterns of fruit on trees and patterns of music. Go and Stop join in with the song and love repeating the chorus, again and again and again!
