==Summary==
===Part 1: "Diaper Change"===
The gang goes to the Fall Festival to see the fall colors, take hayrides, and enjoy the bounty of the harvest. Angelica takes advantage of the fall weather by reminding the Rugrats that a lot of bad things happen as the season rolls in. And something bad does happen, when Grandpa moves out (again) after Stu's latest invention, a Reptar robot designed for the Euro Reptarland amusement park in Paris, malfunctions in his basement. Meanwhile, Chas starts playing "The Dating Game" after Betty gives him a makeover and a date with each one of her looney friends. She also has Phil and Lil switch to super-absorbent diapers.
===Part 2: "Fall Stinks"===
The Rugrats give up on Reptar and bury all their Reptar stuff in the sandbox, because Tommy believes it was because of Reptar that Grandpa left. Later, when the gang visits Grandpa at the retirement community where he now lives, they find that he has been transported to the hospital following a salsa-dance mishap.
===Part 3: "Don't Poop on My Parade"===
Grandpa recovers, but comes down with the "love bug" after a nurse named Lulu brings him back to health. Later, the Rugrats try to stop Fall by stopping the parade, which they do, with a little help of Stu's Reptar robot. And in the audience, someone from Euro Reptarland is watching in hopes that it will become an important part of the theme park.
