In "Swapper", Experiment 355 (Swapper) swaps Lilo and Stitch's minds. When Swapper refuses to switch Lilo and Stitch's minds back into their original bodies, Lilo in Stitch's body travels over to the Mart and attempts to buy a few party supplies there. However, Stitch with Lilo's mind gets thrown out by the manager due to the fact that Stitch's body looks like a dog, and no dogs are allowed in the store. Lilo in Stitch's body then tries to sneak back in the store by hiding under a moving shopping cart, but is quickly found out, chased around, and kicked out again. Stitch with Lilo's mind is then taken away by the dogcatcher, but Lilo manages to use Stitch's body to escape.
In "Ploot", Experiment 505 (Ploot) goes on a rampage after collecting enough trash and pollution to grow into a monstrous form. When Jumba discovers that air freshener spray shrinks the toxic sludge sample in his Petri dish, he and Pleakley head to the Mart to buy more air freshener, which would supposedly neutralize Ploot and shrink him back to his normal size. Jumba and Pleakley manage to find all sorts of air fresheners in the store. When Jumba and Pleakley head to the checkout counter, Jumba tells the salesclerk to hurry with the purchase, but the cashier is unable to find the bar code on the bottom of the aerosol cans.
- In one scene of the ending montage of the original film, Stitch and Nani go shopping at a grocery store, with Stitch riding in a shopping cart. In the scene in question, he trades a lollipop that he's been sucking on with a human baby for the infant's bottle when their carts are briefly parked next to one another, without either's guardian noticing the trade. However, it is unknown whether or not the store in question is the same as the Mart in the series, since the scene is only shown from a single aisle inside.
