The little squirrel Pengpeng enjoys the beautiful music in the forest every day. Sometimes it is the singing of the stream girl "Hua Hua, Hua Hua", sometimes it is the running sound of Brother Feng "Huh Huh, Huh Huh", and sometimes it is the sound of Uncle Big Tree dancing "Shasha, Shasha". But today it heard a strange sound.
The sound was "Gala, Gala" that it had never heard before...
Purpose: Understand all things from sound
