Lax

The Recess Gang, along with their chaperone Mr Boyd, accompany Greta to Hawaii after she makes a big discovery about a new planet.

Meanwhile Lilo and Stitch a local and her alien friend have made a mess trying to create a new recipe. Lilo's older sister Nani orders them to clean it up and then leaves for work however while driving over a puddle Experiment 285's pod was activated. Instead, they try to make Pleakley another alien with a love of cleaning do it. However after seeing how huge the mess is Pleakley faints.

Sometime after Stitch wanders outside and does nothing except lie in a hammock. Then Pleakley is zapped by the same unknown energy that got Stitch causing him to laze about in a similar fashion. The same goes for another alien named Jumba who just arrived.

It turns out the culprit is Experiment 285 or Lax an alien experiment with an antenna-like appendage that is designed to cause people to be very relaxed and lazy. Lilo and a lazy Stitch chase after him but instead find Rigalli running towards the pool of the hotel followed closely by the rest of the Recess Gang. Lilo follows as well but then Mickey and Vance though at separate times are zapped by Lax. Lilo explains everything to C.J. and they then try to capture Lax but they fail and he escapes.

Meanwhile another alien named Gantu is made to follow a satellite's directions to find Lax for the evil Hämsterviel. Lilo and four of the C.J. and Friends characters, Rus, C.J., Greta, and Rigalli catch up to Lax at an observatory. C.J. and Rigalli try to get Lax themselves but they too get zapped. Just then Greta finds the new planet that she discovers but Lilo finds out it is only a satellite being used by Hämsterviel the same one Gantu uses. Greta's Cooper computer is zapped however Greta gets the idea to use the telescope to zap the satellite. While most of the Recess Gang distract Lax by hitting golf balls at him Greta is zapped but she still works on the plan apparently she finds work relaxing. Rus gets chased by Lax but Lilo distracts Lax just in time for Stitch to pummel him. Lilo, Greta and Rus then put their plan into action and the satellite ends up destroyed. Gantu confronts them but Lax zaps him thus ending the threat.

The Recess Gang eventually goes back to normal and Lax finds a hobby in zapping stressed and unpleasant tourists at the airport. Then Rigalli wonders where Boyd is. It turns out Boyd has never left the spa.
