Annie, portrayed by Olive Weeks, is a minor character of The InBESTigators.
Annie is demonstrated as a smart teenager, mainly for her project at the science fair, and is very concerned about people like her younger brother Frank, so she also has a big temper with him because he lost his lunch box and just getting a lot of hot dogs, and she also gets mad at him, especially when Frank confessed that he had taken her experiment, because he was afraid of losing the bet, where he had the intention of exchanging them.
Annie, along with her brother Frank, are punished by their father for not having cleaned the rooms, and they place a bet on whoever has the cleanest room, and that if one of them loses, they would have to pay 50 dollars. Then, Annie decides to interpret their bet at the science fair, where she uses a cotton swab to take several samples and placed them on petri dishes, and formed an ice cream, which is a powder that when mixed with water, he turns into gelatine, which is perfect for bacteria to grow and can prove which of the two rooms is the dirtiest, and also took three control plates from her father's office, in order to compare with the other samples, and the bacteria didn’t grow because the father cleaned it well before. In addition, Frank offers himself as his assistant, where she pays him, and she decides to go somewhere and leave Frank to take care of the samples, however, Frank takes the control plates and hides them in his lunchbox. Soon, when she arrives, she notices that the control boards are gone, and decides to go to the Inbestigators for help, where Ezra is excited to see that the crime is at the science fair, and she says that if someone found out, she would be disqualified, where they accept the case.
