Irvine

 Irvine  is Oscar the Grouch 's niece, a baby Grouch. She stayed in Oscar 's  trash can  while he was away, in episode 2606 of Sesame Street. She has also made many other appearances on the show, up through Season 30. She has a tendency to scream & cry very often. Her parents aren't seen in the series. Whether she is the daughter of Oscar 's brother  Ernest  or  Otto  is unknown.

In Episode 2402, Maria watches Irvine while she's taking her nap for Oscar, who had to go the Grouch supermarket. Unfortunately for Maria, Count von Count wakes  Irvine  up w/ his counting, & Maria can't get Irvine back to sleep. Biff & Sully (mainly Biff) tell her the story of Cinderella, but that doesn't work either. The Two-Headed Monster plays her a violin lullaby, but that doesn't work & they start crying too. Then, when Oscar  returns, he tells Maria, who gives up, there's only 1 way to get a Grouch baby to go back to sleep. He starts yet another argument with Grundgetta  &  Irvine  falls asleep in a matter of seconds. Oscar says Grouch babies love to fall asleep to the sound of a good loud argument.

In episode 3811,  Irvine  insists that she be allowed to take a bath, much to the concern of Oscar. After allowing  Irvine  to take a bath, Oscar  remarks, "She may be clean, but she's still ugly."
