The evil Birdie
Birdie (Adrianne Palicki) is the villainess of "Mayor McCheese Murder" a segment from "Boogie Bardstown in: No Need, I Have Coupons", episode 10.6 of Robot Chicken (airdate October 13, 2019).
The segment began with Mayor McCheese being found murdered in the street. Officer Big Mac and an unnamed rookie officer were on the case with their first suspect being the Hamburglar, who pointed them towards the Fry Guys. Following interrogation, the latter admitted to hearing a "chick" saying that the mayor had reached his expiration date. This, along with the timing of the murder led Officer Big Mac to realise that Birdie was the killer.
After being confronted, the evil Birdie readily admitted to the murder, implying that McCheese had made sexual advances towards her egg daughters. Birdie then began attempting to seduce Big Mac, before drawing a knife from her pocket and lunging at him. However, the rookie officer was able to save Big Mac by shooting Birdie, causing the villainess to drop dead on the floor.
