Yaarp

Yaarp, also known as Experiment 613, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to create devastating sonic blasts that can shatter windows, flatten buildings, and cause acute loss of hearing. Luckily, he can also reduce these noises to soft, gentle honks. His one true place is at Lilo's hula school as an alien invasion alarm and buzzer.

Background

Personality

Despite his destructive nature, Yaarp is quite friendly, but he reacts quickly and dramatically to the way others treat him. For example, if he feels intimidated or provoked, he will emit loud sonic blasts. If he feels safe or unthreatened, he will emit small, gentle honks as a sign of affection and friendship.

Yaarp, for the most part, is pretty easygoing and laid-back. However, he is very ready-minded and cautious, but is loyal to those who win his trust. He is also a bit jumpy and nervous, often sounding his horn at improper times because something trivial had startled him.

Physical appearance

Yaarp is a small, turquoise/blue lemur-like experiment with four arms, small floppy Drowsy-like ears, and a foghorn-like antenna on his head. The antenna, the tips of his ears, and the single ring on his tail, as well as the tail's tip, are all blue. The area around his eyes, his muzzle and chest/belly, and his paw pads are all a lighter variant of his body color.

Powers and abilities

  • Sonic Blast: Yaarp can produce devastating sonic blasts through his megaphone-like antenna. These noises can range from small, gentle honks to massive shock waves that can shatter buildings and cause acute loss of hearing.
  • Bouncing Tail: His tail can act like a spring, as he often bounces on it instead of using his limbs.
  • Yaarp has shown to be skilled in playing the foghorn-like device on his head like a trumpet.

Appearances

Lilo & Stitch: The Series

Experiment 613 was the 613th experiment to be created by Jumba with Hämsterviel's funding. He was designed to use his sonic-blasting ability to cause massive damage and deafen nearby victims. 613 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 613's pod landing in Mrs. Hasagawa's fruit stand.

When Mrs. Hasagawa watered her fruit, 613's pod got wet, activating the experiment. After being admired by a couple on their honeymoon, 613 then proceeded to cause massive chaos using his destructive shock waves.

Later, when Gantu, wearing special earmuffs, chased 613 into an electronics store, the latter was captured in a container, but rescued and freed by Stitch. Instead of showing gratitude, 613 emitted a sonic blast that made Stitch go temporarily deaf, then fled the store with Gantu in hot pursuit.

Since Stitch's ears were highly sensitive to 613's shock waves, Pleakley was chosen for the task, as he did not have ears and was therefore unaffected by the sound blasts. After Lilo, Stitch, and Jumba attempted to train and condition Pleakley, he was equipped with special experiment catching gear. The four tracked 613 down to a cave, where Stitch, using a conch, posed as the experiment and acted like a decoy. He then imitated 613's sonic blast to alert Gantu, who donned his earmuffs and pursued Stitch.

Meanwhile, a reluctant Pleakley entered the cave, where he discovered 613. When Pleakley unintentionally blasted 613 with a vacuum, the latter retaliated using a massive shock wave. However, when a sudden cave-in endangered 613's life, he was then saved by Pleakley. 613 gratefully kissed him three times, while Pleakley christened him Yaarp.

Pleakley and Yaarp soon fled the crumbling cave and made it out safely. When Yaarp first noticed Lilo, he growled until Pleakley assured him that she was a friend, causing Yaarp to emit a gentle honk. Unfortunately, Stitch got captured by Gantu (who thought Stitch was actually Yaarp) during the process, and the latter demanded a ransom exchange.

As part of a setup, Lilo arrived at the local museum with Yaarp in a pet carrier, where the former made Gantu believe that Yaarp was rehabilitated. However (as planned), when Gantu removed his earmuffs and bartered the captive Stitch for Yaarp, the latter unleashed a sonic blast upon Lilo's signal, alerting the authorities and forcing Gantu to flee.

After Lilo revealed Yaarp to the mayor and chairwoman, he was given a one true place as an alien invasion alarm at Lilo's hula school.

Yaarp reappeared in "Elastico" as one of the audience members for Lilo's hula dance.

In "Spike", Yaarp served as the scorekeeper for the Ohana-Rama, and was also briefly seen hiding under the couch during Pleakley's E.A.R.W.A.X. session.

In "Remmy", Yaarp was one of the experiments in Lilo's dream.

Leroy & Stitch

In the film's opening Yaarp can be seen greeting Lilo with sonic blasts from his megaphone-like antenna.

Later, the first 624 experiments, including Yaarp, 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.

Yaarp participated in the following battle between the experiments and the Leroy clones by presumably using his sonic blasts to deafen and push Leroys back.

However, 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe. Yaarp joins them for the song by playing the built-in foghorn-like device on his head.

Stitch!

Yaarp made an appearance in the Stitch! anime special Stitch and the Planet of Sand.

  • Yaarp's pod color is yellow.
  • In "Spike", only Spike, Fibber, Nosy, Bonnie, Clyde, Slushy, and Splodyhead were part of Pleakley's E.A.R.W.A.X. group, but in one scene, Yaarp can clearly be seen hiding under the couch.
