Me, me, ga, ga
igy, ya, ya.
Foodee, shee, shee
La, la, lee, lee.
Mada, dada,
dogie, doo, boo,
Ga, ga, yumm, yumm
wha, wha, shoo, shoo.

Translation:
I'm very happy that I am here
I 've been nine months in a dark warm place.
I can talk but you don't seem to understand me
And when I do, you make such a silly face!

My diaper is wet and filled with some goo
I don't like the feeling, and it's smelly too!
I'm tired now and just want to sleep
and for now goo, goo ga, ga,
Is all that I'll speak!
