Brooklynn is thirteen years old, and one of the six campers attending Camp Cretaceous at Jurassic World on Isla Nublar . She runs the most popular travel and lifestyle blog on social media, with her followers being referred to as ‘Brooklanders’. Due to her large following, Brooklynn was invited to Camp Cretaceous in order to document and post her experiences for her viewership, and to derive publicity for the camp.
Brooklynn would arrive on Isla Nublar via the Ferry Landing along with the other campers, and be greeted by Dave and Roxie. After initial introductions, the campers are driven to Camp Cretaceous by their co-counselors, only stopping briefly as the counselors attempt to recapture an escaped Compsognathus. Reaching the camp, they are given a brief overview of the camp rules, before they get a chance to unpack. That night, all of the campers, including Brooklynn, get a chance to ride a zipline over the dinosaur herd in Gyrosphere Valley.
Brooklynn would later sneak out with Darius and Kenji Kon to what they assumed was the Compsognathus enclosure. As they managed to get onto the installation, Kenji and Brooklynn fight over the phone, resulring in it’s falling into the enclosure. Brooklynn attempts to warn Kenji that it is not the Compy pen, and attempts to open the enclosure after the Velociraptors attack the other children. After Dave and Roxie rescue the boys, Brooklynn’s account contradicts theirs, so they are warned they will be punished if there is another incident.
The next day, the children are taken on a tour of the Field Genetics Labs, where they are introduced to Dr. Henry Wu. Dr. Wu initially prevents Brooklynn from recording in the lab. However, Brooklynn plays on Wu’s insecurity over being in the shadow of Masrani and Hammond to convince him to allow it. Brooklynn conducts an interview of Wu as he introduces himself for her blog and shows her around the lab. Although told that Wu’s office is private, Brooklynn attempts to sneak into it, but runs into Sammy.
She manages to sneak in to attempt to record the contents of his lab. While doing so, she finds that he has kept his computer unlocked, and pores over his files. Upon clicking classified, it sets off an alarm, and the computer shuts down. However, she finds a flash drive and documents referring to the ‘Indominus Rex’, before she is forced to leave after Wu discovers her. Wu forces the rest of the group to leave after this incident. The group return back to the camp for the night, after picking up Darius and Kenji. That night, she is among the group listening to campfire stories, before rain forces them inside.
The next morning, the Campers are taken to Gyrosphere Valley, to help the park personnel lead the herd to their grazing pens. Brooklynn is paired up with Darius in her Gyrosphere, although is too distracted initially by the loss of her social media followers to engage in conversation with him. Initially planning to stay put, Brooklynn is persuaded by Darius to assist in herding a lone Sinoceratops back to it’s enclosure. The lack of coordination from the other campers results in the Sinoceratops sending Darius and Brooklynn’s gyrosphere into the thick of the herd, disrupting the entire herd and causing a stampede.
Darius and Brooklynn are separated from the group, and they encounter the lone Sinoceratops. They exit the Gyrosphere briefly to attempt to approach it, but quickly run back in, just before they are attacked. They quickly become trapped in a sinkhole, slowly sinking as the group discover them. Just as it appears that they will drown, The group then manages to attach a vine through a hole in the gyrosphere to the Sinoceratops, using it’s weight to help pull the vehicle free. The campers are immediately greeted by Dave and Roxie, who proceed to admonish them for their actions and the danger they were in. That night, Brooklynn is editing her video from the day for the blog, and she discovers she has captured footage of Sammy secretly taking a sample from the Sinoceratops.
The next morning, the counselors leave the children alone, as they attempt to contact Claire Dearing. As the campers settle into waiting, Brooklynn confronts the group and accuses Sammy of stealing her phone, but Yasmina steps in to defend her. The group is distracted by the sound of an approaching dinosaur, and they decide to head to the observation tower to try to determine where the roar is coming from. The campers successfully break into the tower, as Brooklynn uses a hair pin to pick the lock, and climb it, seemingly relieved to see the noise is only a Brachiosaurus feeding.
Just then, two employees emerge from the jungle and alert the children to come down. Initially refusing, the kids watch horrified as the Indominus Rex ambushes and kills the two men. As the hybrid attacks the tower, the group attempts to use the zip line to escape, although the emergency brake trips, leaving some of the group stranded in the center. The Indominus succeeds in knocking down the first tower, along with the line, sending the campers, Brooklynn included, falling down to earth. The campers awaken after being briefly disoriented, and make a run for the camp, only to find that it has been destroyed. Brooklynn publicly confronts and accuses Sammy again in front of the group, demanding her phone back, and revealing her earlier incursions into the park security. After some deliberation and bickering, the group decides to head towards the main area of the park to seek assistance. The group continue walking, with the new objective to go to the Field Genetics Lab to seek shelter,
