When Lincoln imagines what would happen if he didn't tell her the truth, she gets a job at Flip's Food & Fuel and has a uniform consisting of a red jumpsuit and cap after she quit her knowledgeable ways when Leni became even more intelligent than her.
When Pop-Pop wants to video chat with his grandchildren, Lisa first tries dressing up as a combo of Lucy and Lana that she calls "Lancy".
Then she dresses up as Luan. When their parents found out about their little charade, their punishment was to go about their tasks while still dressed as the siblings they covered. She had to continue her academic speech in her Luan costume, but her stick pops flowers out and the gag flowers on her costume pour water on the audience, ruining her speech.
When she researches the upcoming tornado, Lisa wears a yellow hat and raincoat.
When reenacting the pioneer days with her siblings, she still wears her pants and shoes, but she now wears a white jacket, a green vest, a black Western bow tie, and a tan hat with a green band, which seem to resemble a snake oil salesman. She even wears small glasses in front of her normal glasses.
