Summary
On Kimi's 2nd birthday, the babies search for her birthday cake without knowing that their parents are holding the cake!

Plot
The episode begins at the Pickles' home, where Chas and Kira are planning Kimi's birthday party at a birthday place known as the Happy Castle. Didi has made a birthday cake, a Reptar-themed ice cream cake for Kimi's birthday. Taffy announces that she has to leave her babysitting job early because her band has a gig at a teenage castle club. Chas, Kira, and Didi leave for the Happy Castle and Stu was left to bring Tommy, Chuckie, Phil, Lil, and Kimi there; however Stu accidentally brings the kids to Taffy's gig due to him not paying attention because of his newly invented P.U.S.S (Pickles Ultimate Satellite System). As Didi and Stu try to figure out where the other is using the P.U.S.S. the babies look for things at the club that would seem fit for Kimi's birthday (balloons and cake). Didi, Chas, and Kira come with Dil and the ice cream cake and while looking for the kids the children find and eat the melted remains of the Reptar ice cream cake; the adults later find them and enjoy the party. The episode ends as Taffy sings a birthday song to Kimi.

Trivia

 * This is the third and last episode in the main series to focus on a character's birthday. The first was "Tommy's First Birthday", and the second was "Angelica's Birthday".
 * Depending on when the episode airs, that is supposedly Kimi's birthday.
 * This is also the last episode of the original Rugrats series on television, making it the 'series finale'.
 * This is also marks the final appearance of Tommy, Chuckie, Kimi, Phil, Lil, Taffy, Dil, Stu, Didi, Chas and Kira in Rugrats.
 * This is also the final onscreen appearance of Taffy as she doesn't appear in Preschool Daze, All Grown Up! and the 2021 series.
 * All Grown Up! makes sense since the babies would be too old to have babysitters.
 * Chuckie gets the final line of Rugrats: "Happy Birthday, Kimi!".
 * Didi and Stu both had the first line in the series which was Happy Birthday Tommy.
 * This was episode 172b in production order, making Rugrats the longest-running Nicktoon until the SpongeBob SquarePants episode "Squiditis" aired in 2012.
 * Chronologically by airdate, the honor goes to the episode "For Here or To Go".
 * For the longest time, this episode and its sister episode "Fountain Of Youth" didn't rerun on NickRewind for unknown reasons until June 3, 2021, when they were finally aired. The block aired them again on June 24, 2021, which means that they will remain and continue to air regularly on the NickRewind block.
