Milo Murphy's Halloween Scream-a-Torium! is the 35th episode in the first season of Milo Murphy's Law. It aired on October 7, 2017. It serves as the series' first Halloween episode.

Episode Synopsis

Zack doesn’t think anything about Halloween can scare him anymore, but he didn’t account for Murphy’s Law.


Part 1

Milo turned a decommissioned truck into a haunted house for Halloween and invited his sister and friends to check it out. Zack states that he outgrew Halloween. The first "scare" was Diogee in the costume Brigette made for him to wear to Veggie Fest. Meanwhile, Dakota and Cavendish discuss Halloween and how it vanished out of existence sometime in the early twenty-first century. The two decide to have a good time that night and learn about the holiday. Back at the haunted house, only Sara is freaked out and it starts to move. Elliot sees the truck and rides after it on his bike. After Zack decides to see what's going on he walks out of the back, which is over a cliff, and is soon joined by Milo. The segment ends with a cliff-hanger.

Part 2

Milo and Zack pull the truck to safety with a grappling hook and are met by Elliot, who says they committed almost twenty safety violations. The truck then heads downhill backwards and through eight different warehouses. Dakota realizes he lost the time grenade, then Cavendish realizes that they are the reason Halloween no longer exists in their time. So they track down the kid who now has the device - which was easier said than done.

The truck then lands in the courtyard of Jefferson County Middle School, improving the party planned by Mort and Chad. The time travelers finally find the time grenade and Dakota manages to disarm it, but not before sending him and Cavendish to Ancient Rome. Dakota succeeds in saving Halloween but inadvertently takes away February twenty-ninth so that it only occurs once every four years, creating leap years. Back in Milo's time, Zack has finally learned to enjoy Halloween again. Then his dad shows up in a fish costume. After Zack runs off, Elliot compliments Marcus' costume.
