Urobilin the Yellow
A silly bouncy song about why pee is yellow — a real word called urobilin, made from broken-down red blood cells, and worth saying twice
SPLISH SPLOSH!
I went potty, looked on down -- Yellow river, yellow town! What's the why of yellow pee? Sit right back -- I'll tell you, see!
Urobilin! Urobilin! (yer-oh-BY-lin! yer-oh-BY-lin!) Urobilin! Urobilin! That's the yellow that's coming out-of-in!
SPLISH SPLOSH!
Inside you, RED blood cells go zoom -- Carrying air to every room! But cells get OLD -- they wear, they tire -- The body says: time to retire!
Tiny workers come and break 'em down -- Sort the parts, save the gold and brown -- Recycle the iron -- save the rest -- And one little leftover comes through the test...
Urobilin! Urobilin! (That's a big word -- a science win!) Urobilin! Urobilin! The yellow leftover sliding right in!
(Travels through the kidney filter --) (Kidneys clean -- they don't dilly-dilter --) (Out it goes -- the river bright --) (YELLOW! Right? YELLOW! That's right!)
SPLISH SPLOSH!
Old red cell? Goodbye! Iron stays! Don't cry! Urobilin says HI -- On its way to the sky!
(Or, you know -- the bowl.)
Urobilin! Urobilin! (yer-oh-BY-lin! yer-oh-BY-lin!) Urobilin! Urobilin! Old red cells in a yellow tin!
(Now -- big science-kid pride moment --) (Ready?)
URO-BY-lin! (say it twice!) URO-BY-lin!
(Look at you!) (Big word kid!)
SPLISH SPLOSH!
