"A Yummyful Day" is a Sesame Street song from a 2003 episode. The song starts off the street scene; Cookie Monster waltzes down the street singing about his feeling of having a day full of having cookies to eat. A verse of the song is sung at the end of the story by Cookie and Cookie Hood as they go to Hooper's Store for some cookies.
- An instrumental version of the song is used on the main menu of the DVD, C is for Cookie Monster.
