One of the few times on the series (or on any Nicktoon for that matter) where the entire 30-minute block is filled with 1 long story, rather than 2 shorter 15-minutes one.
As the pilot, there are a few differences from later on in the series. For instance, Tommy wears a read shirt with overalls rather than his usual blue shirt. Likewise, Angelica is considerably less mean and spoiled than her later appearances (though there are a few moments here and there that hint at her later attitude).
The series premiere it introduces all of the major characters, with the notable exceptions of Chaz Finster (Chuckie's dad) and Charlotte Pickles (Angelica's mom) as those characters haven't been introduced yet.
This episode debuted on the same date as the other two original Nicktoons shows Doug (1991) and The Ren & Stimpy Show (1991). Doug (1991) was the first to air, then Rugrats (1991) and then The Ren & Stimpy Show (1991) .
The scene where Angelica gets her picture taken by Didi with Tommy and Chuckie was later added as a front cover of the first Rugrats tape "A Baby's Gotta Do What A Baby's Gotta Do", released in 1996 despite this episode is not included in that tape. Also, on the tape's front cover, Tommy is wearing his normal blue shirt instead of the red shirt he wore in this episode.
