The Rugrats try to stop Fall by stopping the parade, and they do, with a little help of their former friend, Reptar. And in the audience, someone from Euro Reprar Land is watching, in hopes that it would become an important part of the new theme park. Meanwhile, Grandpa recovers nicely, but ends up coming down with a new disease -- the "Love Bug" -- after a nurse named Lulu brought him back to health. In a bizarre twist, this wasn't the first time they met, yet it was the first time they knew each other.
