I'm a bad bad bunny.
— Dr. Colosso
Phoebe joins the cool group for a class project on China only to find out that they're not interested in working as hard as her. Max joins Phoebe's usual group and tries to take a free ride while the rest do all the work. Billy and Nora try to prove to their parents that they're just as good as them in taking care of the house.
In class, Phoebe and Max are studying Chinese culture. Mrs. Austin asks the class to break into groups for their class projects on Chinese culture. Max tells Phoebe that he loves group projects because he doesn't do anything. He wonders which group to join. He considers joining Phoebe's "nerds" group. Max starts making fun of Phoebe but Phoebe tells him to call them whatever he wants. There's no other group she'd rather be in.
Phoebe is ready to join her usual group of Sarah, Evan and Tyler. But then she is torn when the popular girl Winnie Lee finally asks her to join her group with other popular girls, Sabrina and Emma. Max manipulates Phoebe by whispering into her face until she finally chooses Winnie's team. Sarah is disappointed that Phoebe ditched them for the popular girls. However, Max takes Phoebe's spot in Sarah's team, which makes Sarah even happier. Phoebe apologizes to Sarah doesn't take it kindly.
Max tells Sarah that he is excited to be part of her group. He then walks away. Sarah forces him to come back. She asks Max to take this project as serious Sarah takes their forbidden love. Max agrees. Sarah asks Max for his project idea but Max manipulates Sarah to say what she wants after which Max says they were thinking the same thing. He even calls Sarah babe and pretends to love her. They agree to do Sarah's Chinese Dragon idea.
Meanwhile, Phoebe tries to get her group to focus on their project but they're all on their phones. She suggests meeting at the library but Sabrina asks if that's the new opened place. Winnie then concludes that Phoebe is right - they should all meet at the mall. Phoebe gets mad because that's not what she said.
A few days later, Sarah's group is working on their Chinese Dragon project outside the Thundermans garage. Max sits in a comfortable chair where he asks the rest of the group to refill his drinks. Evan and Tyler are concerned that Max isn't doing anything. Sarah goes to confront him but after getting closer, she admits that it's getting hot and she wouldn't mind if Max wore a tank top. Phoebe arrives from the mall and congratulates Sarah's group on their good work. Sarah asks her if she thought they wouldn't be able to do it without her. But, she explains that she thought Max would have dragged them down. Sarah asks Phoebe how her group is doing and Phoebe lies to her that they're working really hard. But then Winnie comes to drop off Phoebe's clothes that she bought during their shopping at the mall. Phoebe feels embarrassed that they haven't started the project.
Sarah asks Max to put the dragon back into the house after it dries before it rains. Tyler suggests they should come back and do it themselves. But Sarah doesn't like their distrust of Max. Would someone with dimples you can swim in let them down? Max agrees to do it. It starts raining later at night and Dr. Colosso wonders if he should tell Max that the paper dragon is still outside. Max wakes up, wonders if there's something he's forgetting but Colosso tells him to go back to bad. Colosso praises himself for being a bad bad bunny.
With one day left before project presentations, Phoebe tells her group of the ideas she came with that they could do overnight and still get an A. But the girls tell her that they only want to get a C. She tries to get them to meet but they give fake excuses. For example, Sabrina lies that she has to babysit her baby brother - but she's an only child. Busted! Phoebe stands up to them and forces them to put some effort or else she can't work with them. They agree. To let her go. After Winnie, Sabrina and Emma kick Phoebe out of the group, she tries to get into Sarah's group but Sarah refuses.
Phoebe tells Mrs. Austin that she had a little snafu with her group and now she has to go solo. Mrs. Austin reminds her that part of the project is to test her ability to work with a group. So, she will fail the assignment. Meanwhile, Sarah's group comes in shouting at Max after discovering that he left the dragon outside all night. Max takes off his shirt to distract Sarah with his tank top. Sarah loses focus because of Max's muscles. Tyler and Evan take off Sarah's glances. Now she can't see anything. But the truth. Sarah stands up against Max and kicks him out of the group. She tells him that he's still allowed to date her but they can never work together again. After her powerful speech, she bumps into the door before getting her glasses back.
Mrs. Austin watches the whole thing and realizes that Max's problem has solved Phoebe's issue. Phoebe thinks that Mrs. Austin will give her Max's spot in Sarah's group but instead asks Phoebe and Max to start their own group of two. Max asks Phoebe to get them at least a B and walks out. Phoebe gets angry.
At home, Phoebe says she won't work on their project until Max helps. Max says he will stand and watch until she cracks. He starts eating apples, waiting for Phoebe gives in. After Max eating at least a dozen apples, Phoebe finally caves in and agrees to do the project for them. She is doing a project on Chinese food.
While making the Chinese food, Phoebe gives Max a very powerful speech about why he sucks. She says Max is not lazy looking for an easy A. He is just afraid to try. The only reason he wants to be a supervillain is because he couldn't be a better superhero than her. He thinks it's easier not to try than to try and fail. That should be his motto. Phoebe messes up her Chinese food and Max asks her to focus instead of focusing on him. Phoebe sends Billy to super-speed to China and steal a Chinese dragon. She gives it to Sarah's group as an apology for ditching their group and letting Max ruin their project. During presentations, Winnie Lee presents about how her and Emma's and Sabrina's shoes and other items are all made in China. Mrs. Austin shuts them up. But she still gives them a C. Next up, Phoebe and Max's group but Max isn't there yet. Mrs. Austin asks her to present anyway.
For their presentation, Phoebe takes out her Chinese egg rolls but messes up and drops them on the floor. She starts collecting them as she realizes that she is going to get an F. Then there's fireworks outside spelling out Chinese characters. Max enters the room and explains the use of fireworks in Chinese history. Max says that they worked on the fireworks project with Phoebe. At first Phoebe tries to deny it thinking that they will get in trouble for setting fireworks in school ground. But when Mrs. Austin likes the project, Phoebe proudly takes credit. Max lies to Mrs. Austin that the Chinese characters spell Phoebe's idea, "It's better to try and fail than to not try at all." The Thunder Twins get an A.
After the presentation Phoebe thanks Max for doing the right thing when it mattered most. She asks Max to tell her what the Chinese characters really mean. Max says that they mean, "Phoebe smells like a wet donkey." Clever!
Hank and Barb check their to do list for the things they need to do. Then Billy falls down a floor board, remind the parents that they need to fix the floorboard. Nora then calls out the parents for being lazy. Hank adds "ground Nora for being sassy" to their to do list. The kids continue complaining and showing the parents the other things they haven't handled well. Nora challenges Barb and Hank that she and Billy can do a better job at running the house. The parents accept the challenge, only to prove to Billy and Nora that it's not as easy as they think.
The parents wake up the following morning to find that Nora and Billy have fixed the floorboard and even prepared breakfast. Barb and Hank discover that Nora have done way much more in the house in one day than they've ever done. They are scared of losing the challenge to Billy and Nora because they can't leave in a world where the kids run the house. So, they result to sabotage the house until the kids give up. Barb and Hank start breaking everything in the house.
When the parents finally admit they've lost the bet, Nora takes charge of the house and orders them to clear the house for a guinea pig farm.
