After Scott the Undergrounder and Mrs. Murawski appear to hit it off and set up a date, Milo and the gang attempt to help the former look more presentable and normal.

Hollywood is rebooting the first Krillhunter movie with all women, so Milo and the gang help Tobias Trollhammer audition as a woman. Meanwhile, Cavendish and Dakota try to catch an alien while picking up trash by the highway.

While heading to a mentor program she doesn't want to be a part of, Melissa ends up paired with Savannah on a mission to stop a rampaging robot that Milo and Zack accidentally built at the science fair before it destroys half of Danville.

After discovering a boombox in the attic, Milo, Martin, and Grandpa Murphy go camping so Milo can undergo a family rite of passage to become a "Murphy Man". While the men are away, the Murphy women and Doof go to an art museum to celebrate the day without Murphy's Law, but Doof causes chaos in its place.

After Zack breaks his leg getting tangled in a harp while doing interpretive dance, all of his friends plan a "cast party". At said party, everyone shares stories of how they all broke something without Milo, Martin, or Murphy's Law around; as far as they know.

Zack and Milo join Melissa's athletically minded wrestling, speech, and debate team.

Milo faces down a cosmic storm made of negative probability ions, while Melissa, Zack, Cavendish, Dakota, Perry, and Doof work their way through the alien populace to save their friend.
