The Rugrats and their families go to Stu & Drew's old cabin on Lake Crackanee, where, as kids, Stu & Drew first met Chazz. After seeing some old movies of themselves as kids, Stu wishes that they were young again. The wish, of course, became a mission for the Rugrats, who started searching for "The Fountain Of Youth", which, they claim, can turn their parents into little kids. It's all fun, until Angelica told the Rugrats that, once their parents become babies, she'll be the one in charge.
