中文版：
Yummy Yummy 令我食得停不了
Yummy Yummy 誘惑我早餐未了
眼睛一開 便見到 你的微笑
全日無精打采亦全無需要
我愈來愈好 飲食愈來愈好
要跟你比賽 食量愈來愈好
全日都抱著我 便會好快樂
我飲啖水都係你個笑聲好
我咪一咪眼你便會知我咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪咪
英文版：
Yummy yummy, I can't stop eating it
Yummy yummy, tempting my breakfast yet unfinished
Open my eyes and see your smile
No need for me to tire myself throughout the day
I'm getting better and better, and my appetite is increasing.
I want to compete with you for the most appetizing.
I feel contented all day long, holding you close to me.
Even a sip of water is your laughter.
As soon as I blink my eyes, you will know.
Blink, blink, blink, blink, blink, blink...
