Barbie: Skipper and the Big Babysitting Adventure

After Skipper's imaginary rescue fantasy, she fails to keep the children quiet while moving them away. A food fight breaks out in her living room, and the parents arrive to witness the chaos. This incident leads to negative reviews and cancellations, threatening her babysitting business.

Skipper needs a new job because her babysitting business is struggling after the negative reviews. When she asks Barbie for help, Barbie reveals she's leaving for volunteer work in the rainforest for most of the summer. Skipper then decides to look for alternative employment and finds the water park opportunity.

Tammy is the boss at Oceans Extreme water park who initially interviews Skipper and Joy. However, Milton, the park owner, overrides her decision and hires Skipper directly. This creates tension, and Tammy becomes jealous and competitive, attempting to undermine Skipper throughout the summer.

Tammy pitches a gaming bus idea to Milton as a way to attract children and generate profit. However, the plan is revealed to be a scheme, and Tammy pressures Milton to fund it while Skipper grows wary of the arrangement. The bus driver Pete waits outside for Tammy's decision.

The park introduces a new unmanned, auto-piloted birthday party plane as a spectacle. A flight attendant mistakenly lets children ride in, believing they are flight testers. When Erica activates the take-off, the test flight spirals into chaotic adventure with the kids inside.

The plane is introduced earlier as part of the park's newest attraction.

After the chaotic flight, a sandstorm forces the group to rely on problem-solving skills while searching for a safe way back. Dolphins guide them along the Malibu coastline and help steer them back to the park, where Milton sees the children are safe.

Tammy's scheme is exposed when the chaos unfolds, and her plan begins to unravel. She learns to advocate for children's needs instead of pursuing her own agenda. Skipper encourages Tammy to take initiative, and they agree to work together on the pool cleanup to help younger kids.

Skipper's babysitting skills prove essential during the chaotic birthday party, boosting her confidence. Milton approves a hands-on daycare solution at the park, and Skipper and her friends form a babysitting squad ready for new adventures. The experience transforms her struggling business into a successful venture.

Joy clashes with Tammy when Tammy pushes customers to the front and barks orders for a customized smoothie. The situation escalates when the blender lid isn't put on properly, resulting in a mess. This incident leads to Joy being fired and sets up her friendship with Skipper.

Cheri, a hopeful dog walker, joins Skipper, Joy, and Anna to propose a doggy day care at the park. The group envisions this new service attracting families with younger children. Milton shows support for adding a daycare area, though Tammy attempts to block progress.

In the opening scene, Skipper envisions herself saving the children of Malibu from the 'evil Stacie' and her friends. She dramatically flings Stacie into the sky before vanishing. This fantasy establishes Skipper's desire to be a capable babysitter and sets up her heroic ambitions for the rest of the story.
