Olive and Otto look for a pattern that might explain the mayor’s musical outbursts.

Queen Goo and King Berry sit down to a nice lunch together…when another Goo calls Ms. O! She’s forgotten that she’s scheudled a meeting with Baroness Goo too. Otis, Olympia and Miss O must find out what all three Goos like to eat for dessert so that they can prevent headquarters from being covered in goo!

Ms. O calls in a favor. She asks Mr. Fonts, Party Pam, Hopkins, and Logan the Ogre to watch headquarters while the agents are at their company picnic. They agree. Their only jobs are to sit down, do nothing, touch nothing.

Otis and Olympia question Queen Goo and King Berry on what they like to eat. Queen Goo likes foods that are the color orange, like traffic cones and life vests. King Berry only eats things in the shape of spheres, like beach balls and Christmas ornaments. Otis and Olympai use a venn diagram to figure out what food is both orange and spherical – a food both Goos can eat.

Ms. O has acciedentally scheduled meetings with Queen Goo from the Land of Goo and King Berry from Goo Land at the same time! And when the Goos get mad, headquarters gets goey. Olympia knows just what brings people together – food! They’ll have a lunch meeting. Olympia sets off to find out what kinds of food each of the Goos like so that she can serve them something they both enjoy.

Ocean tells Oona about the time the Cherry-On-Top-Inator saved his life.

Olive is training to become Ms. O and run her own Odd Squad. Otto is assigned a new partner, Ohlm. Ms. O asks Otto and Ohlm to figure out a pattern to determine where a Spidercat will strike next.

Ms. O needs someone to be Captain Fun. Otto and Oren both want the job. Odd Squad holds an election to decide who it will be. Oksana volunteers to be Otto’s campaign manager and Polly Graph tallies the votes.

Dr. O and Odell use data collection and a chart to develop a theory for what is causing the odd outbreak.

Agents are still making strange noises, but Dr. O and Odell are collecting data to help identify the source of the odd outbreak. Since the infected agents can’t talk, they must communicate by playing charades.

Otto’s favorite band has a new song, “Take Away Four.”

Logan the Ogre sticks his hands into a vat of toxic waste – and when he pulls them out, he has lazer hands! Every time he raises his hands up, he shoots lazers, destroying parts of headquarters! The team decides to use the map Ms. O gave them to find gloves to put over his lazer hands.

When Hopkins uses the evil copy room by accident to make copies of his Shmumbers Carpet presentation, the copy machines come alive and try to attack everyone! The team must stop the copies before headquarters is destroyed – and to do so, they must use their map. Following the map’s directions, Hopkins goes around the back of the copiers, and turns off the evil copy machine leader from behind.

Olympia tells a story about how Orson saved Odd Squad. She and Otis had a really difficult case. They had so much information, they didn’t know how to sort it all. Orson showed them with his blocks that making a bar graph would help them organize the information. They did – and solved the case! Orson can’t be fired – he helped to save Odd Squad!

The evil agent combines all the stolen gadgets to create the blackholeinator – and it’s destroying headquarters! The agents have to figure out what gadget to take away to make the blackholeinator do something else. Meanwhile, the evil agent is getting sucked into the black hole – and might take Ms. O with him. Maybe Otis can save the day.

The agent helping the villains reveals himself, and explains why he plotted to overthrow Odd Squad. There was a time when he wanted to be good – but when he graduated from the academy, he expected to be made The Big O right away. He was told that was ridiculous – one day maybe, but not right out of school. This infuriated him! As vengence, he decided to help the villains destroy Odd Squad.

The team looks through all of the agents’ files to figure out who was in HQs for every single villain break in. They cross out every agent one by one until there’s no one left! But wait – they’ve forgotten someone…

Olympia and Orchid are handing over their gadgets to Ohlm so that he can put stickers on them when Oona appears. She’s figured out that Otis must be innocent! There was a villain break-in before Otis worked at Odd Squad, and one when he was out sick. He couldn’t let villains into HQ if he wasn’t there! There’s someone else at HQ letting the villains in.

With Otis and Ms. O accused of being villains, The Big O assigns a new Mr. O. to run headquarters. Meanwhile, Otis and Ms. O are being given a warm welcome at Todd’s Home for Villains – a place where bad guys go when they just want to be regular guys.

Oona has been living in a broom closet for six months, hiding from a giant plant outside. While in the closet, she figures out the pattern – the gadget numbers in this world are flipped in the tens and ones places. So that means that Oona has to find the gadget that has the same numbers as the dimensionator – but flipped. The only problem is, the giant plant is blocking her way!

Oona experiments with gadgets in an attempt to figure out which gadget will act like the dimensionator. At first, she thinks that the gadget number multiplied by ten equals the gadget in the real world. But that theory turns out to be wrong. She needs more data! When Oona tries out the napkininator, its turns out to be the growinator – and a plant starts to grow into something giant and alive!

Ms. O tells a story about how the hyraclops were out to attack Odd Squad. The agents tried to throw eggs yolks at them to scare them away, but the hydraclops ducked, and the eggs missed. The agents were about to abandon headquarters when Ms. O noticed that something about Orson looked…a little different. It turns out, Orson had a secret that would save Odd Squad.

Oona accidentally zapped herself with the dimensionator gadget – and now she’s in another dimension! The problem is, things don’t work the same way in this world. The light switch down means the light is on, and the gadgets don’t do what they’re supposed to. Will Oona ever get back home?

Owen tells a story about a mission. The agents were getting hungry waiting for a villain to show. Owen volunteered to get food, but the agents couldn’t agree on what to eat! Some wanted pizza, some wanted hotdogs, and some wanted sandwiches. Owen didn’t know how to organize all the information. Then Owen spotted Orson eating pie, and realized that he should put the info into a pie chart.
