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