Finsterella (Rugrats, 1991)

"Chas: Chuckie, Kimi. There’s something we’d like to tell you. Now I don’t know if you can understand this, sweetheart (Kimi), but I’ve adopted you. Kira: And I’ve adopted you, Chuckie. Chas: What that means is, we love you so much, we want the world to know that we’re a family. - Heartwarming moment revealing Chas adopted Kimi and Kira adopted Chuckie"

"Finsterella" is the first episode of Season 7 of Rugrats.

Plot
When Chas reads "Cinderella" to the babies, Chuckie gets scared by the fact that he also has a "step-sister" and "step-mother". He begins to see other parallels in his own life to those in the story. When the Rugrats say they're going to a party and Chuckie isn't invited, it's only a matter of time before his "fairy bob-brother" shows up and Chuckie imagines himself in the fairy tale. - Description from Klasky Csupo.

Why It Rocks

 * 1) The animation and voice acting are still passable.
 * 2) There is good continuity in this episode, referencing the 2nd movie, Rugrats in Paris, with Chuckie saying "No." while in the present of the adults, Tommy mentioning when they were at the church in Paris, and Kira mentioning Coco.
 * 3) Some funny moments in the episode, like how Kimi copied Fifi’s and Phil’s actions, the cookie scene with Angelica and Kimi, and Chuckie dressing himself up.
 * 4) Many of the characters are still likable, including Tommy, Chuckie, Phil and Lil. Chuckie as he tried to see the best in the day with the help of his friends and shows his love for his family, despite the mean-spiritedness of his sister (acting like Angelica), and his friends for comforting Chuckie and helping him out.
 * 5) The episode is still well-written unlike what this season would later become.
 * 6) Chuckie’s dream is a good and funny parody of Cinderella.
 * 7) The moment where Tommy, Phil and Lil call out Kimi for being mean and acting like Angelica was very satisfying.
 * 8) At least Kimi told Tommy, Phil and Lil what she was doing, and they helped her find Chuckie, and when she did find him, she brought him to the party. That can be her way of making it up to him for the way she acted earlier, showing she does at least care about him.
 * 9) The very heartwarming moment when Chas and Kira brought Kimi and Chuckie to the party, and revealed that Chas adopted Kimi and that Kira adopted Chuckie to everyone, wanting the world to know that they are a family.
 * 10) A good ending where Kimi and Chuckie play together, and everyone having fun at the party.
 * 11) While she did get away from karma in this episode, Angelica did get her comeuppance for her actions in the next episode, "Angelicon".
 * 12) The episode started Season 7 on a HIGH note and it could've been a great season if it wasn't for all the negativities that happened during the season.

Bad Qualities

 * 1) Kimi is sadly quickly flanderized already in this episode, and this is her first appearance outside the movie. In fact, both she and Angelica are at their absolute worst in this episode, as they both teased and tortured Chuckie, and were both very mean-spirited towards him, as Angelica was her usual bratty self, while Kimi was just doing it for her own fun of amusement of copying Angelica, when her brother and friends know better than this.
 * 2) * In fact, Lil definitely knows about this, as in a season 3 episode, "Twins' Pique", she decided to act like Angelica simply because she didn’t want to be too similar to Phil and be mistaken for him, but then soon understands why it isn’t a good idea to be like Angelica, and resists throwing her dad’s calculator into the mud, even when Angelica tried to tempt her into doing it.
 * 3) * Unlike Kimi, and most episodes of the show, Angelica got away with her actions in this episode. Thankfully, she gets her comeuppance in the next episode.
 * 4) * Thankfully, Kimi does quickly learns that Angelica is bad and mean, and she never copies her actions again, and she did make it up to Chuckie after she was called out for her actions by her friends.
 * 5) This can be seen as a sort of torture episode for Chuckie, as Kimi and Angelica were being mean to him while Kimi was copying Angelica.
