Nok Tok's narabug likes listening to the songbird's song. When the bird flies away, Nok Tok's narabug is sad. Nok Tok promises he will go and find it. However, Nok Tok keeps finding reasons to stay with the other Piplings.
When the cheebies arrive, Nok Tok admits he is worried about being lonely on his trip. So they all agree to search with him and help keep Nok Tok's promise to his narabug.
