Lyrics
Kanji= 1 2 3 4 We Are Cells at Work 1 2 3 4 We Are はたらく Fuu!

今日も運ぶよ 酸素　酸素 体中の隅から隅へ だけど広くて　迷子　迷子 手助けされてるはたらく細胞 さあ、行こう！

はたらくぞ！はたらくぞ！ 毎日毎日修行中　Ooh!

今日も雑菌　排除　排除 細菌ウイルス出てこいや！ 絶対逃がすな　遊走　遊走 プロフェッショナルなはたらく細胞 さあ、行こう！

はたらくぞ！はたらくぞ！ 毎日毎日戦場

３７兆個の一人 次に会えるのはいつかな？

誰かのために　誰かのために 一生懸命　一生懸命 あなたも私も必死に働いてる みんなのために　みんなのために 命がけだぞ　命がけだぞ プライド持って　健・康・第・イチ

世界平和を 厳守 厳守 仕事は多岐に渡りますよ 命令受けてテンションアップ やる気 元気 本気出すはたらく細胞 さあ、行こう！

はたらくぞ！はたらくぞ！ 毎日毎日ドラマティック

異常はないか チェック チェック やれやれ一息入れますか

「ふ〜. 」 「おつかれ. はい、お茶. 」 「あ、どうも. 」

さあ、行こう！ さあ、行こう！

はたらくの？はたらくぞ！ なんだかんだ仕事が好き好き

やるべき事をやり抜くため 泣かない 負けない 死なない 諦めない

誰かのために　誰かのために

一生懸命　一生懸命 あなたも私も必死に働いてる 生きてくために　生きてくために 全力だそうよ　全力だそうよ 使命は一つ　健・康・第・イチ

誰かのために　誰かのために 一生懸命　一生懸命 あなたも私も必死に働いてる みんなのために　みんなのために 命がけだぞ　命がけだぞ プライド持って　健・康・第・イチ
