The Mysterious Wind - S1.E12

Randy and ChaCha are relaxing in the park when Randy feels a strong wind. He asks ChaCha where wind comes from and where it goes, but ChaCha can only give a scientific explanation which Randy obviously does not understand. So he tries to follow the wind and is surprised to hear music. A cellist was practicing for a music contest but Randy thinks it is the wind singing. ChaCha tells Randy that maybe it is a song by the Wind Fairies. At the music concert, the cellist plays the Wind Fairies' song. As he starts to hum along, everybody in the audience does, and the evening ends on a high note. Randy and ChaCha have reached their conclusion. Winds go to where there is a lot of fun and excitement, just like the both of them do.
