The Zubble-Wump song is the song that Megan Mullaly and Grandpa Mullally sing to Horton the Elephant about what a Zubble-Wump is. The Little Cats start in too. The whole song is about Great Grandma Mullally telling everyone she knew that she doesn't know, don't care and but that no one else has one or will get to see it hatch. As they go on they name off some animals that it wouldn't be.

It was featured in The Wubbulous World of Dr. Seuss episode "The Song of the Zubble-Wump."
