This article will cover episodes from Seasons 3 through 5. Hang on to your diapies, Rugrats fans!
1. 'Cool Hand Angelica'
Angelica is surprised when she finds herself struggling to fit in at Susie's Day Camp.
Watch It Because: One of the first episodes to show a more sympathetic side to Angelica.
Fun Fact: It is widely known that Arlene Klasky, one of the creators of Rugrats, did not like Angelica in the early episodes, thinking her too much of a bully. "Cool Hand Angelica" was likely an attempt to soften the character. Klasky had warmed to Angelica by the time The Rugrats Movie was produced.
2. 'Grandpa Moves Out'
Feeling under appreciated, Grandpa Lou moves to Flushing Waters, a seemingly luxurious retirement home. While visiting, Tommy and Angelica cause chaos in their efforts to wake up all the "tired" people.
Watch It Because: A rare episode in which Tommy and Angelica are united in their goal.
Look Out For: Roberto Mazlatan, The Flushing Waters spokesman, is a parody of actor Ricardo Montalban.
3. 'The Stork'
After being informed by Angelica that new babies are delivered by a Stork, Tommy mistakenly believes that a bird's egg he finds is his new baby brother, naming him Milton.
Watch It Because: The series of humorous misadventures the babies get into while caring for Milton make this a must watch.
Foreshadowing?: While Milton is, of course, not Tommy's baby brother, Tommy later gains a real baby brother, Dil, in The Rugrats Movie.
4. 'Angelica Breaks A Leg'
Wanting more attention during a week's stay at her Aunt and Uncle's House, Angelica feigns a broken leg.
Watch It Because: The classic scene of Stu making pudding for Angelica at 4:00am. It has inspired many memes, and Youtube Poops.
Look Out For: The young Doctor treating Angelica, Dr. Hooser, is an obvious parody of Doogie Howser, M.D.
5. 'The Last Babysitter'
While Stu, Didi, Randy, and Lucy attend the Dummi Bears Rock Opera, Susie's teenage sister Alisa is left to babysit. But once the adults depart, strange things begin to happen.
Watch It Because: The three older Carmichael siblings receive more character development in this episode.
Look Out For: Tommy's voice actress, E.G. Daily, also voices Susie in this episode, as Susie's regular voice actress, Cree Summer, was not available. Kath Soucie, the regular voice actress for Phil and Lil, voiced Buster and Alisa.

Watch It because: A fun superhero parody.
After everyone becomes trapped in the attic of the Kropotkin House, Grandpa Boris tells them the story of Passover.
Watch It Because: A fun, educational special.
Fun Fact: "Passover" was originally the final episode of Rugrats, and the only episode to air in 1995. The "Chanukuh" special aired late 1996, with the series resuming production soon after, due to Rugrats repeats getting higher ratings than anything else on Nickelodeon.

All Angelica needs to do to win a role on her favorite TV Show, "Miss Carol's Happy House," is to correctly say the Word Of The Day on camera. She overhears what she believes is the real word from a grumpy Miss Carol, only to discover that it is a "bad" word.
Watch It Because: A wonderfully funny episode, and probably even funnier to re-watch as an adult.
Look Out For: Vicki Lewis, who voiced the foul-mouthed Miss Carol, later returns in the role of Miss Weemer, Angelica and Susie's kindergarten teacher.
18. 'The First Cut'
