Experiment #375 has been activated; a phantom-like experiment that can inhabit and animate inanimate objects. So when it gets loose in the family's house, it inhabits Lilo's toys and creates all sorts of mess, for which Stitch gets the blame. Can they catch the real culprit, or will Stitch be blamed for everything?

Experiments #501 and #502 are both activated at the same time, a water sprayer and a lava sprayer. Unfortunately, Lilo and Stitch are having some problems with each other, and soon decide to split apart, with Lilo teaming up with Pleakley, and Stitch teaming up with Jumba. Can the 2 capture the experiments without their partner?

Stitch won't listen to Lilo's advice about trying to see the good in people, and will go to any lengths to stop him capturing an experiment pod, including racing to a neighbouring desert island, with Lilo, Jumba and Pleakley in tow. But after the camp of the 'hunting parties' are destroyed, Stitch and Gantu blame each other. Turns out it's an experiment. Who will capture Splodyhead?

Stitch has been recently very successful at capturing and repurposing the Experiments, but it's gone to his head. He thinks he's too good for everything and is being a royal pain.

But things are set to change when Pleakley goes into Jumba's ship and sees an experiment pod with the number '627' on it. Jumba has been making a new experiment. Luckily, it's in containment. That is, until they leave the ship and it escapes! Now it's employed by Gantu and Stitch wants to prove he's better than it. But he just gets beaten, and as 627 can't be turned good, Lilo and Stitch are in trouble...

Experiment #523 - Slushy

A giant heatwave has struck Kauai. Lilo is trying to get Stitch to try something to escape the heat, but Stitch just refuses: He's a creature of habit, and won't try new things. As he tries to get a cold sofa, he activates Experiment #509, an ice experiment from the elemental series, who has frosty breath that can transform any town into a frozen one.

Experiment #297 - ShortStuff

Stitch is getting really upset about people thinking he's too short, so Pleakley uses Jumba's growing ray to make Stitch bigger. Meanwhile, an experiment is activated and it is soon short circuiting mechanical devices all over the island.

Experiments #149 - Bonnie and #150 Clyde

Bonnie and Clyde, two stealing experiments, are activated at the same time and are stealing stuff all over the island. Lilo and Stitch decide to leave their room secretly after they are sent there after getting in trouble. They run into Bonnie and Clyde and the two experiments soon convince the two to do some not-so-nice things while the steal stuff. Will Lilo and Stitch get caught, or will Bonnie and Clyde?
