| Character Information
Sloan is a member of Addy's crew. She is British.
Lisa and Addy ran into Bella-Ella, Sloan and Tessa Rose when they were riding horses around Addy's fields. The three girls then mocked Lisa before they went off on their horses. Addy then told Lisa that even though they seemed cliquey and stuck up, they were nice once you got to know them. When Addy was opening presents, Sloan got her a pair of sunglasses from New York City. After Addy opened up Lisa's gift, which was a toy horse, all four girls mocked Lisa for giving Addy a toy.
Sloan and her friends were mean to Lisa all through the sleepover, mocking her and uploading embarrassing videos of her to social media. When Lisa was trying to call Grampa for help, Sloan and her friends took Lisa's phone and kept it away from her before throwing it high up. When Bart arrived to help Lisa, Lisa put horse hoof hardener onto the hair of Sloan and the other girls. When they woke up, their hair broke off and they gave chase to Lisa and Bart on horseback.
When the girls caught up with Lisa and Bart, they threatened to destroy Lisa on social media. Lisa then got through to Addy who helped Lisa by pulling the strings on the other girls vests, causing them to inflate and the girls to fall off their horses. As they were on the floor, Sloan and the others talked about how mean Addy was just then, which made them want to be her friend.
