🎵 Luyện Nghe Bài Hát: Henoglobin Highway - Phineas & Ferb OST

 Just  two of us,
  an esophagus,
 It's time to get this  rolling,
 I don't  make a fuss,
 But that was 
 Slow  before we reach the colon,
 On  Hemoglobin Highway,
 In a mini  (mini submarine),
 If  going my way,
 You'll see what  mean,
  a left at the spleen!
