Rugrats

A baby duck hatched in Tommy's backyard, and the first thing it sees is Chuckie. Chuckie adopts the duck, which he calls ""Herbert"". At first, caring for Herbert was exciting, but when the novelty wears out, it becomes a chore. Meanwhile, Betty and her environmental group protest at a condo site that left the baby duck's mother without a home, while Grandpa tries to win at checkers.

Spike's attempts to save Dil from immenent danger gets Spike in trouble with Stu & Didi.

Dil and Angelica steal the affections of the adults because they are beautiful and cute, so Chuckie decides to turn into a butterfly to be beautiful and cute too.

In order to get two Cynthia toys Angelica pretends that she has a twin to get double of what she wants. Everything goes well until the babies like her twin better then her so she decides to go back to being herself.

Angelica Tells Tommy that Susie's ( imaginary ) sister Yvonne disappered of giving all her toys to Susie. Tommy and Chuckie think he will dissaper, and take the toys away from Dil and Didi.

Angelica drafts the Rugrats to play her ballet troupe, so she can stage her own ballet recital to prove that she can dance. She did this because (1) she lied to Susie about taking dance lessons (Angelica was expelled from dance school after 2 classes), and (2) she did this to get back at Susie, who was chosen to be a lead at her class' presentation of Swan Lake. Angelica's biggest challenge is to get Chuckie to wear a tutu; he didn't want to, as he feels embarassed wearing one (obviously). The end result -- ""Angelica Lake"", with a pail of water for a lake, and Dil in his high chair as a tree. Meanwhile, Stu, Drew, Randy & Chazz work on Stu's roof, having trouble finding out what caused the roofing tiles to deteriorate.
