She's 11 years old too and has been sitting behind Dennis all the time since the 1st grade in Science class. Her first official appearance was in "Kat of Diamonds" in the second season, but she appeared in other episodes of the series over the first season as a background character and has appeared in the classroom, the streets, or one of all that girls who laugh at the "weird" things that Coop does.

In Bringin' The Heat where Burt showed a film about his childhood a girl who looks like Estelle appears. Possible explanations:

  • Estelle's mom looks like her as a kid
  • Estelle is a time traveler. (latter less likely)


She has brown, long and straight hair, with black glasses (like Millie), a rose-red shirt and a dark red skirt, with school shoes and a white skin tone.


  • She is the fourth person in the city who knows about Kat being evil.
  • At the last part of the episode, she saves Dennis from a Kat's attack
  • She feels ignored by Dennis.
  • Her dressing style is like Millie's style but without the bow.
  • She becomes friends with Fiona in the episode Kat of Diamonds.
  • She is regularly featured in backgrounds and groups
  • Some fans believe she has a crush on Dennis.
