Scrooge, beginning to feel old, goes to look for the fountain of youth.
This episode contains examples of the following tropes:
- An Aesop: You're only as old as you feel.
- Continuity Nod: The "Fountain of Youth" actually just reflects the person as they were when they were younger. Launchpad sees himself as he was when he left home some time ago.
- Evil Is Not Well-Lit: Discussed; Launchpad says they'll be all right as soon as the sun comes up because "everyone knows ghosts can only do their haunting at night."
- Fountain of Youth: Scrooge looks for the literal Fountain of Youth so that he can live longer. It turns out that the fountain only makes a person look younger when reflected in its waters.
- Nice Job Breaking It, Hero!: The others inadvertently make Scrooge feel old at his birthday party (such as by giving him a rocking chair), which provokes The Quest for the fountain of youth.
- No Name Given: The antagonist's name is never given.
- "Scooby-Doo" Hoax:
- The ghost is a man trying to scare people away so he can find the fountain of youth.
- Huey, Dewey, and Louie dress up as a ghost to scare the antagonist.
- Worthless Treasure Twist: Scrooge goes off to find the fountain of youth. When he does find it the fountain doesn't really make him young, just his reflection.
- You Just Had to Say It: Louie asks what they're going to do. One of his brothers says, "Follow [the ghost]". Louie comments that he "had to say it."
