I'm sorry, I couldn't find the complete lyrics for the song "儿歌联唱2（洪波编曲）" in the web search results. The closest match I found was a YouTube video of the song[^3^], but it doesn't have the lyrics in the description or the comments. Maybe you can try to listen to the song and write down the lyrics yourself, or ask someone who knows the song well. I hope this helps. ?
