— Officer Walnut to Piper
She is portrayed by Dayna Dooley.
Officer Walnut is an adult who has black hair, blue shirt, black tie and brown eyes.
In Secret Room, she appeared at Hart's house along with Lacy, who had an injured arm. They brought Piper in handcuffs. Then they explain to Jake the reason, then they force Piper to cook soup. Later, when they return to the Hart house, Piper gives them the pot with soup, although it almost spills due to the tremors, then when they are out of the house with the pot tremors occur again, so they spill the soup although they tried to avoid it.
In Sister Twister, Part 1, she was in an alley with Piper, she orders Piper to do community service, as a penalty for stealing a baby elephant. Walnut tells Piper that she must fill the trash bag to finish her job, when Piper asks her if she can pay someone to do it for her, Walnut laughs and leaves.
In Escape Room, she arrives at the Hart House when Piper was about to go to the escape room opening. She orders Piper with babysitting her nephew, Miles, and niece, Mika, as part of the community service Piper was supposed to do.
