If you are looking for the song, sung by Wakko and Yakko Warner, go here.

Heloise Nerz[1], better known as Hello Nurse is the buxom studio medic, over whom Yakko and Wakko continually fawn. She works with Dr. Scratchansniff. Her voice actress is Tress MacNeille who also voices Dot.


Hello Nurse's apparel consists of a small white nurse's cap and a white form-fitting dress, alongside white high heels with ribbons. She has long blonde hair and big blue eyes. She wears violet eyeshadow and red lipstick.

Hello Nurse's appearance almost always prompts Wakko and Yakko into exclaiming "Hellooooooo, Nurse!" (one of the show's well-known lines) and jumping into her arms. They will also call out her name if they see a beautiful woman as shown in several episodes. Dot does likewise when an attractive man enters the picture. (Dot usually says "Hellooooo, Nurse!" or as seen in Jokahontas, "Hellooooo, Mel!")


Hello Nurse is considered by Yakko and Wakko to be hot, loyal and intelligent. Aside from her beauty, Hello Nurse is supposedly an outright genius; in the song about her it states several of her rather prestigious accomplishments (although parts of it may be not true, since the Warners were hit by lightning after they stated they would be if they were lying). She stated in Wakko's Wish that she has a "mean IQ of 192". In later characterizations, she thinks that she is respected only for her looks outside of her mind. However, in a song about her, both Wakko and Yakko seem to show that they greatly respect her for her mind, but also love her for her looks quite a lot too. She, like everybody else, sometimes finds the Warners annoying, but mostly recognizes them as absolutely cute kids. In the comics, Hello Nurse was also a secret agent.


Animaniacs (Original Series)

Pinky and the Brain

Animaniacs (Reboot)



  • Hello Nurse originally didn’t have a name in the original series. It remained unknown until 2020, when Tom Ruegger revealed it to be “Heloise Nerz”. Her character is called Hello Nurse because Yakko and Wakko address her as such.
    • The Warners' Lot Song marks the first time someone implies "Hello Nurse" is her name.
      • Even though Yakko and Wakko call her Hello Nurse, Dr. Scratchansniff calls her Miss. Nurse, implying that her last name is Nurse. Though later confirmed to be quite close to it.
  • Originally, Hello Nurse was supposed to be a zany individual who thinks that she's a nurse.[2]
  • In the film Wakko's Wish, she and Dr. Scratchansniff were friends and had a working relationship as she's always seen by his side. After things get better in Acme Falls, they’re both finally able to make money and get their own homes.
  • In the Hello Nurse song, Wakko says her IQ is 157 but in Wakko's Wish she says her IQ is 192. Since Wakko and Yakko were struck by lightning, this means that Wakko had most likely made a mistake about her IQ.
  • Through the "Goodbye, Nurse!" credits stinger in episode 99; Hello Nurse's name is the last word spoken in the original Animaniacs.
  • In "Dot the Macadamia Nut," her eyes are fully black.
  • In the fifth and final season in the original series, the color of the cross on her cap changed from red to purple, possibly to avoid legal issues with the International Red Cross and Red Crescent Movement. Despite the change, her visual cameo in the 2020 reboot segment "Santamaniacs" depicts her cap with its original red color.
  • Animaniacs reboot hello nurse

    Hello Nurse's cameo in "Santamaniacs", which is the only time she is seen in the reboot.

    Despite not appearing physically in the 2020 series, she is mentioned in three segments and has a picture cameo in one segment.
    • In Anima-Nyet, the Russians parody Hello Nurse as "Female Medical Professional," and Dot asks, "Is that supposed to be Hello Nurse?"
    • In Hindenburg Cola, Dr. Scratchansniff says that Hello Nurse left Warner Bros. to join Doctors Without Borders, explaining her absence.
    • In Santamaniacs, Yakko briefly holds a picture of Hello Nurse and Minerva Mink citing him and Wakko becoming "less naughty" following their "mysterious" disappearances. This is the only visual appearance of Hello Nurse in the reboot.
  • Tom Ruegger said that, had he worked on the reboot, he would have made Hello Nurse surpassing Thaddeus Plotz and being promoted to CEO rather than creating Nora Rita Norita.[3]
  • A character that shared a similar design to Hello Nurse was featured on an episode of The 7D on Disney Channel. It is worth noting that The 7D had a lot of the same creative team as Animaniacs.
