Anne has built a brand new observatory and invites Nick and Shania to a sleepover so they can witness the lunar eclipse. First, Nick needs to get permission from his Mom to spend the night at the junkyard. The kids decide that it's time for Nick's Mom to meet Anne's Dad.

Anne is working out the kinks with newly made Pal, while Nick, Shania and the other androids play Hide and Seek. When Nick accidentally activates a security program that makes Hand, Eyes and Pal go into super-hiding mode, the kids have to find the missing androids before Pal's circuits overload.

It's Shania's birthday and Anne is making her a cake from scratch. Nick's Mom gets a job offer on the other side of the country and Nick has to decide whether or not he wants to make the move while Shania is up for a part in a movie.

When uploading Magnus 22 blows the junkyard's power grid, the junkyard is left without power or security. Anne, Nick, Shania and Anne's Dad have to figure out another way to power the junkyard or the androids will be defenseless. As a cold night looms, Anne and her Dad sleep over at Nick's house.

Anne, Nick and Shania discover that Ada has deleted Magnus 22 but they figure out there's a backup of its programming at her house. They go undercover at her son Dylan's party to save Magnus 22 and bring it back to the junkyard.

Anne has plans to camouflage parts of the junkyard, but Shania wants to make art with the androids. Nick works on his science project at home, but gets a surprise visitor when Charlie shows up... with a lot of questions about Pal.

Anne gets an assignment from school that instructs her to "get closer to one of her dreams." She's not sure what it means, but Nick and Shania help her figure out that one of her dreams is to make contact with alien life. To help Anne get closer to that dream, they experiment with how to send one of the androids into space.

When Nick's Dad cancels a winter getaway up North, Nick is upset. Anne and Shania try to make it up to Nick by building a machine that demonstrates the phases of matter to make snow and ice -- so that the kids and androids can have a winter celebration at the junkyard.

When the kids realize it's their one year anniversary of being friends, they decide to throw a party to celebrate. But, Ada shows up with a surprise gift for Anne that has one mission: to get Pal to Magnus Tech.

Anne is planning a series of experiments with dry ice, but her plans are interrupted by an invitation to Charlie's birthday party. At the costume party, Anne is excited to find dry ice so she can finish her project. Meanwhile, Nick and Shania have to keep Charlie from finding out about Pal when Pal decides to tag along.

Anne experiments with growing plants but her crafty robo-mouse eats her experiment. Nick, Anne and Shania devise ways to catch the robo-mouse while the androids discover a stray cat in the junkyard. Hand, Eyes and Pal hilariously try to apply what Anne says about plant-care to taking care of the cat. But once Anne shows them that animals have different needs than plants, they take better care of the cat and want to keep her. Nick realizes the cat is the perfect solution to Anne's plant problem but, unfortunately, the stray has already moved on. Now the question is, will the cat come back?

A woman named Ada comes to the junkyard to buy something from Anne's Dad, and the two discover they share a passion for robots. Ada invites Anne to visit the lab where she works, and shows her a big world outside the junkyard.

Anne has recreated Nikola Tesla's plasma ball for her summer school project. Before they can get Anne's plasma ball up and running, the power goes out in the junkyard. Anne decides to try alternative types of energy (sun, wind and people power) to generate electricity for her Plasma Ball. Meanwhile, thanks to Shania's fixation on a popular singer, Hand develops an interest in the electric company truck that comes to fix the power lines... can androids feel love too?

To make amends with Nick's Mom, Anne and Nick work on fixing her car while she runs errands with Anne's Dad while Shania trains Fangs.
