"**I Know What You Did Last Slumber**" is the first segment in the seventeenth episode of the first season of ***Hailey's On It!***. It is also the thirty-first episode of the series overall and premiered on October 14, 2023 on Disney Channel.

Plot
Hailey is inviting her friends Becker, Lucy, and Kennedy to a sleepover which they all happily accept. She attempts to invite Tina, but she already has other commitments to an online crafting session. Scott, of course, is on edge about the girls doing something without him, while A.C. arrives to inform everyone that he acquired a new jet ski that he will be using for an upcoming water show. Obviously, no one is interested in his plans. The whole sleepover turns out to be part of the next item on Hailey's list, to pull an all-nighter. The girls are having fun, but Kennedy tucks in for the night early and the girls are unable to prank her due to her fortified sleeping bag.
Hailey, Becker, and Lucy all decide to pull a prank on Scott instead by exploiting his fear of werewolves. The prank works and the girls next pull a craft bomb on A.C.'s jet ski. Just as they are walking away however, the jet ski comes loose, rolls down a hill, flies off a cliff, and explodes. Traumatized, the three decide to get rid of the evidence and act like nothing happened. In the morning, Kennedy awakens, completely oblivious to the events of last night. Hailey succeeds in her all-nighter, but does not tell Beta or Scott what happened. The next day, A.C. bemoans the loss of his jet ski and Kennedy decides to take it upon herself to solve the case, much to Hailey's concern.
The girls begin seeing googly eyes (used during their craft bomb) everywhere before the jet ski is fished out of the ocean. The beach police have concluded that Tina is the culprit due to her crafting session. Hailey decides to come clean and reveals that she and her friends were the culprit, but Kennedy stops her. She concludes that it was A.C. himself. His mother is the real owner of the jet ski as A.C. himself is too short to ride it. She also reveals that AC never actually entered the water show, but after boasting about his skills to the whole town he unlatched the jet ski, resulting in its destruction, to give himself a face saving way out of having to answer for his lies, proving it by revealing the lynchpin stored in the functional hidden pocket of A.C.'s vest. Exposed, A.C. is taken away and forced to do five hours of beach clean up during the water show. Hailey is relieved and Scott reveals that he was leaving googly eyes everywhere because he thought they were cool.
