Sample, A.K.A. Experiment 258, is an illegal genetic experiment created by Jumba Jookiba. He is designed to annoy his victims by recording random sounds he hears and replaying them in endless loops, using his nose as a microphone and his mouth and ears as speakers. His one true place is providing backbeats for Fox Roswell, an originally rhythmless musical group.
Sample is a lively, upbeat experiment. He is usually happy and easily amused by his own music and any other sound, commonly dancing by bouncing from one foot to the other. His perky, carefree attitude may be a result of him being blissfully unaware of the situation at hand. He also shows great curiosity towards any sound that is unfamiliar to him. He doesn't like to be silent unless he can play his music (or any sound) to amuse himself. He normally just tends to do his own thing, completely disregarding the simple command to be quiet, yet following complex instructions during a rescue mission. He doesn't have a real voice (he can only dub someone else's voice), but finds a way to communicate through his backbeats, head nods, and basic hand signals.
Experiment 258 was the 258th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to annoy enemies by recording, replaying and looping random sounds that he hears. 258 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai, with 258's pod landing on a golf course.
When a golfer mistook 258's pod for a golf ball, it was whacked into a pond, activating 258, who recorded and sampled the noises of a parrot and frog, scaring the golfers.
258 then sampled the sound of a jackhammer and casually made his way to town, where he was almost captured by Gantu, who was looking for the experiment. However, 258 was instead caught by the dogcatcher, who took the former to the dog shelter, mistaking him for a dog.
The dog pound lady contacted Merwin and Dean, two alien hunters who eagerly accepted 258 and almost took him to an alien convention. However, when Lilo and a reluctant Stitch arrived at the pound to get Stitch his shots, Merwin and Dean, seeing that Stitch was an alien too, attempted to grab him to take him to the convention as well. When Lilo and Stitch saw 258, they decided to rescue him from the two alien hunters.
Lilo, Stitch and 258 managed to escape Merwin and Dean, but they soon caught up. However, Gantu intervened, causing Merwin and Dean to try to catch him as well. They chased Gantu, forgetting about Stitch and 258.
Safe for now, Lilo, Stitch and 258 arrived home, where Jumba explained 258's powers. Due to the latter's powers, Lilo decided to name 258 Sample, whom Stitch locked in the closet after his cacophony grew annoying. Afterwards, Pleakley headed out to the alien convention with Jumba tagging along.
Sometime later, Gantu came to the Pelekais' house looking for a place to hide from Merwin and Dean. Lilo and Stitch hesitated, but complied after Gantu promised to behave. When the two alien hunters arrived, Sample began sampling random noises, despite Lilo and Stitch's best efforts to silence him. Everyone then escaped out a nearby window, but Gantu got stuck halfway and was captured by Merwin and Dean.
Lilo, Stitch and Sample went back to rescue Gantu, but he blasted the trio into a net and then put Stitch and Sample into containment orbs. Lilo reprimanded Gantu's betrayal, but he revealed that he had called a truce with Merwin and Dean by allowing them to showcase Stitch and Sample, the latter of whom they would give back to Gantu in return.
Stitch and Sample were taken to the alien convention, where Merwin and Dean planned to have them be shown in front of an audience to prove aliens were real. However, Stitch escaped and released Sample. Gantu unsuccessfully tried to stop them from running away. Merwin and Dean then forced Gantu to pose as an alien in front of the entire audience.
Sample was later found a one true place providing backbeats for the band Fox Roswell, whose rhythm was initially out of sync.
In "Snafu", Sample was one of the experiments that joined Lilo and Stitch on a mission to rescue Gantu's captive experiments. Sample stood watch outside Gantu's ship and was told to crow like a rooster if the coast was clear, while the others broke into the ship. While he was standing guard, Experiment 120 somehow convinced him to imitate the ship's alarm, thus alerting Gantu to their location.
The first 624 experiments, including Sample, were rounded up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
Sample participated in the following battle between the experiments and the Leroy clones.
The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song "Aloha `Oe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Despite appearing prominently in certain intros of Seasons 1 and 2 of the Stitch! anime, Sample only appeared in one episode of Season 3: "Jessica vs. Yuna". In this episode, he was "transmutated" by Hämsterviel so that instead of just repeating the sounds he hears, he can fire waves of light yellow dust from his ears, causing anyone it touches to dance uncontrollably when he plays his music (similar to Carmen's ability).
He was given the assignment to use his ability to get Stitch to the top of a hill, where a pre-built transportation device would be waiting to send him to Delia. He managed to form a parade out of several people he affected, including Jessica, Toriko, Makiko, Hiroman and his entire soccer team, and even Stitch. However, when he tried to use his power on Yuna, the dust reflected off of her umbrella, hitting him and breaking his spell on everyone. Stitch was then able to use the spandex-covered inside of the umbrella to absorb Sample's dust and dump it on him, knocking him unconscious.
He was then placed in a machine built by Jumba that would reverse the transmutaion, but he still used his dancing power on Yuna when a little bit of the remaining dust from the umbrella fell on her. Stitch then discovered that the machine wasn't plugged in, but decided to enjoy Yuna dancing for a while, despite her protests.
Eventually, Sample was reverted back to normal. He was then dehydrated and stored in Jumba's vault until he was needed again.
- Sample seems to always be smiling and can apparently tolerate anything, including being captured.
- Sample appears, along with several other Lilo & Stitch characters, in a parody of the Disney Channel Original Movie High School Musical, which was broadcast as part of the High School Musical: Around the World one-year anniversary special.
- Sample's pod color is white.
- Sample is described by the experiment computer screen as, "Experiment 258. Primary function: Sonic annoyance. Drives people mad by sampling sounds and repeating them in an endless, grating rhythm."
- Sample's ears appear in the online game Jumba's Lab.
- Sample bears some resemblance to Loudred and Noivern from Pokémon, even having the same speakerphone-like ears and themed with loud noises.
