Avoiding them all, the team finds Leona, strangely aged to an old woman, who leads them to the mythical Fountain of Youth! The KND are amazed at the prospect of remaining ten years old forever, but the Delightful Children desire nothing less than to destroy the Fountain, claiming that the goal of all children should be to grow up.

    Notes (13)

    • In this episode, it's learned Numbuh 1 originally had brown hair, but an incident with the DCFDTL caused him to be permanently bald. Numbuh 5 blamed herself for this happening as a result of not there to help him when he needed it. From that time on, she's devoted herself to helping kids no matter what.

    • We learn when Numbuh 4 was younger, he looked similar to his little brother Joey

    • Based on the episode, Numbuh 4 does well in Gym, considering he managed to get them past the Gym part of the ancient school

    • Second time the KND's and DCFDTL's age was changed. The first time was in G.R.O.W.U.P

    • Team episode, but more centered around Numbuh 5.

    Trivia (2)

    • Going in range from youngest to oldest after being changed by the fountain of youth water, Numbuh 3 was youngest, followed by Numbuh 1, Numbuh 2, Numbuh 4, and Numbuh 5.

    • In some parts of this episode, Lenny's helmet was completely red with no white stripe.

    Allusions (2)

    • Leona: You... have to find the fountain...
      This is a reference to the game Golden Sun, likely. There's a point quite late on when you find a man who's lived to be over 150. He tells you he's lived off magical draught, and is almost dead from a recent lack of it. You are then sent to get it, in a similar way that Leona said that line.

    • Fountain Of Youth Secret Passage: Harry Potter
      There is a secret passage in the girl's bathroom activated by turning a knob on the sink. It's probably a reference to Harry Potter And The Chamber Of Secrets.
