The Letter O was introduced in Discover Feelings. The song features a orange chimpanzee (Wiley in the actual volume) singing about the letter O.
Lyrics
O. You beautiful O.
You great big beautiful O.
You're. My favorite vowel I found because.
Your big and round or oval O.
You beautiful O. You great big beautiful O.
When you are inside when people really loat.
Without you nobody could ride a boat. O (4x)
Oh you beautiful O.

Of all the great things you do, O.
You beautiful O.
You great big beautiful O.
When I'm surprised, you're all alone. Oh!

O your beautiful, you round and wonderful.
Oh you beautiful O.
