Her life gets turned upside down during her New Year's celebration when she is visited by a scientist who hails from the future and learns that the completion of a long list of tasks she wrote will be the important start of a chain of events that will lead to her inventing a device that will be used to save the entire planet by reversing global warming.

[8][9] Now, Hailey must overcome her fears, complete impossible and impractical tasks, and face her feelings toward her best friend, Scott Denoga.

[9] However, some of her accomplishments will be threatened by Chaos Bots, small robots from the future sent by a mysterious villain who wants to prevent her from finishing her list and saving the world.

"The Last Sand": Hailey and her father enter a sandcastle-building competition, giving her an opportunity to complete an item on her list by winning it.

Eventually, A.C. reveals a giant fan to blow away her castle, but Beta brings a squadron of pelicans to dump water on A.C.'s.

However, one of the Cubix Dudes injures his wrist, and the group recruits Scott, who turns out to have a talent for solving Rubik's cubes, to take his place.

Throughout the trip, Kristine feels uncomfortable and left out and ultimately breaks down when she loses her favorite hat in the restaurant's ball pit.

Hailey and her friends do a project of renovating the lighthouse and seem to succeed, but it ultimately goes wrong and produces light resembling a disco ball; however, this makes the site attractive as an event venue, and Patricia decides not to sell it.

While both guys get to the hottest sauce in the array, Javier ultimately wins, but Kristine then takes control by eating the legendarily hot Black Scorpion chili pepper whole, and then dances with Scott.

"Flippin' Out": To distract from the failure to capture a Chaos Bot, Beta suggests that Hailey get a varsity letter to complete another item on her list and improve her physical skills.

The two of them manage to get along fine, and when Hailey mentions that she and Scott are planning to buy some Wild Katz, a brand of sneakers, Becker promises that she can get them for her.

However, their plans are soon put to a halt when Kai and Patricia remind Hailey that she promised to babysit her younger brothers, Dwayne and Johnson.

"Seas the Day": Scott is depressed over Kristine breaking up with him, so Hailey decides to cheer him up by taking him to Catalina Island, with Beta suggesting that they eat at a restaurant so that she can be open with her feelings.

Hailey initially fails to cheer Scott up, but after a near-death experience, he returns to his usual happy self and they go to eat at the restaurant.

To make up for it, Hailey takes Scott and Beta to Jurassic Journey, a low-budget theme park, which in actuality she is using as an excuse to find the material she needs to complete the device.

Hailey apologizes for shirking Scott, but he is happy that they completed an item on his list: see a real kaiju fight.

In a bit of irony, Scott wins a Golden Dingle while A.C. learns that the Swag Bros do not want to develop his app any further due to their laziness.

"I Know What You Did Last Slumber": Hailey holds a sleepover with Lucy, Becker and Kennedy so that she can complete a list item that has her pulling an all-nighter.

The authorities blame their friend Tina for the crime, but Hailey comes clean, only for Kennedy to conclude that it was A.C. himself who detached the jet ski causing it to get destroyed.

Despite her disappointment, Hailey continues to instill the positive belief in everyone that mermaids exist and A.C. is humiliated when people publicly share his photo (he wanted to make money from it).

Due to Scott's inattentiveness, Hailey gives him a pair of her backup glasses so that he can focus on her bright catcher's mitt.

"Out of Body Slam Experience": It's Beta's pre-birthday and Hailey got him a VIP pass to meet wrestler Rowdy Russ Stanton.

Hailey decides to cheer her up by taking her to a spa where Kristine undergoes a hallucination of a Yoga Goat telling her to find the thing that she "loves" most.

She finally snaps at Bacon in front of the assembly, until she learns the real reason she never wins: she forgot to turn in an overdue library book.

"The Biggest Luger": Scott is invited to join Ingebretsen Academy to be a part of their prestigious luge team as he is considered a "legacy".

A shorts series centered on Hailey, Scott, and Beta going on a road trip in the Professor's car to visit the clown museum.
