Lyrics:

Tapi-Tapi-Tapioka! 
Everybody come and meet my delicious friend! 
It’s so tasty and amazing and I’ll share my song for you to see 
Singing out for tapioka, tasty and refreshing! 

Momma always buys me tapioka
Drink for a little surprise, happiness in every bite 
No such thing as too much tapioka! 

Eat and be healthy, drink and be happy! 
Now and forever, tapioka’s all I’ll ever need 

Going out to search for tapioka, gonna drink it up, whatever I can find— 
"Ah, my tummy feels so goo~d, tapioka’s always so goo~d"

So sing it,
tapi-tapi-itapi-tapi-tapioka! 
Everyone raise your cups and stand up!
Drink it and let’s say hey! (hey!) 
Sing for your favorite taste! (hey!) 
Everybody loves the yummy-ness of Tapioka-kun! 

So sing it,
tapi-tapi-tapi-tapi-tapioka! 
Everyone raise your cups and stand up!
Drink it and let’s say Ah!(Ah~!) 
Drink til the very last drop!(Ah~!) 
Everybody loves the yummy-ness of Tapioka-kun!
