[Chorus]
Hap, hap, hap, happy birthday
Hap, hap, hap, happy birthday
We'll sing our cheer for another year
It's a happy birthday to you

[Refrain]
You live in a zoo
(You live in a zoo)
You live in a zoo
You live in a zoo, a zoo, a zoo, a zoo

[Chorus]
Hap, hap, hap, happy birthday
Hap, hap, hap, happy birthday
We'll sing our cheer for another year
It's a happy birthday to you
