"Bowser Junior's New Room!" is the 450th episode of SML Movies.
Bowser brings his son and Chef Pee Pee to the kitchen, telling him not to eat the last donut that he has. When Bowser leaves, Chef Pee Pee tempts Junior into eating the donut. Junior does and Bowser finds out. Junior tries to explain to his father that Chef Pee Pee was tempting him into eating the donut but ends up improperly explaining the situation to him. Bowser then drags Junior to his room where he punishes him for his actions by revoking his toy and phone privileges while explaining to him that stealing from others is wrong and that actions have consequences.
Joseph then arrives and asks Junior to go out and ding-dong ditching with him. But it was just a scheme set up by Bowser to get Junior into trouble further and to presumably teach Junior a lesson for what he did earlier. Afterwards, Bowser punishes Junior harder by consequently banning Junior from his room much to his dismay and confusion.
After a few minutes of sleeping with Junior, Chef Pee Pee went to Bowser to complain. Bowser told Chef Pee Pee that he'll make him a bed and Chef Pee Pee is really happy.
Eventually, Bowser made a bunk bed for both Chef Pee Pee and Junior. And the video ends with Junior further irritating Chef Pee Pee before finally going to bed.
