Hunkahunka, A.K.A. Experiment 323, is an illegal genetic experiment created by Jumba Jookiba. He is designed to cause anyone he pecks to fall in artificial love with the first person they see, whether the victim and love interest are either the same or opposite gender; only water in the victim's face will break the spell. He was captured by Gantu, but was rescued in "Snafu". His one true place is in a heart-shaped birdhouse with the local online dating service.
Experiment 323 was the 323rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to use his fake love-inducing ability to bring entire civilizations to a lovestruck standstill. When 323 pecks someone, and he/she sees somebody, his/her eyes start flashing hearts and imagines himself/herself standing under palm trees shaped into a heart while holding the hands of the person he/she fell in love with; then the hexed victim says, "I think I love him/her," if the love interest is distant, or "I think I love you," if he/she is right in front of the person. 323 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.
At an unknown point, Experiment 323 was activated off-screen (possibly by an ocean wave).
Later, Gantu attempted to capture 323 after noticing the experiment, but was thwarted by Lilo and Stitch. 323 then pecked Gantu to make him fall in love with Pleakley, while Stitch managed to capture 323 in a cooler. Lilo, after naming him Hunkahunka, used the experiment's love-inducing power to make Keoni fall for Lilo.
However, Hunkahunka was able to escape and resumed his fake love-inflicting rampage while being pursued by Lilo, Stitch and Gantu. At one point, Hunkahunka pecked Gantu again, causing the latter to temporarily fall for Stitch. While Stitch evaded Gantu, the former recaptured Hunkahunka and attempted to hide him in a raffle box, but he managed to escape again shortly after.
Later, Hunkahunka entered a dance hall, where he caused countless victims to fall in love, and pecked Nani to make her fall for Gantu. Eventually, after a long chase, Gantu was able to capture Hunkahunka in a containment orb. Regardless, Lilo ultimately decided that people should want others to love them for who they are, not merely because some alien bird pecked them.
Hunkahunka was successfully sent to an impatient Hämsterviel, where the former pecked Hämsterviel, causing him to fall for Gantu. However, he still insulted Gantu like he would on a regular basis, implying that Hunkahunka's love powers had a somewhat different effect on Hämsterviel.
Hunkahunka reappeared in "Snafu", and was freed along with Gantu's other captive experiments by Lilo, Stitch, and several other experiments in a rescue mission.
The first 624 experiments, including Hunkahunka, 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.
Hunkahunka participated in the following battle between the experiments and the Leroy clones, as he was seen among the other experiments.
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.
Hunkahunka made an appearance in the Stitch! anime where Stitch used him on Angel after she got mad at him earlier. However, Hunkahunka's spell caused Angel to become too obsessed with Stitch, therefore teaching him a lesson when Hunkahunka also made others fall in love (including Jumba, who was about to reveal the antidote before becoming part of Hunkahunka's spell).
Hunkahunka is a small pink/purple hummingbird-like experiment with a large head, black eyes, dark pink and maroon feathers on his body, a long lavender beak, light pink belly and purple-tipped wings and tail. He stands 3 inches tall and is light, weighing under 5 lbs.
Hunkahunka causes artificial love by pecking a target that causes them to immediately fall in love with the next person they see, regardless of gender.
To be more specific, Hunkahunka injects the victim with a love-inducing drug that affects certain nerves, causing an artificial "love" sensation in which they are attracted to the first person they see.
The effects of Hunkahunka's love-inducing pecks can be reversed by spraying water in the victim's face. Also, his pecks kick in when the victim sees somebody, so if the whole place is dark, the pecks will not have effect immediately.
- Hunkahunka was first revealed in a DVD bonus feature of Stitch! The Movie in the experiment gallery.
- Hunkahunka is named after a lyric in the Elvis Presley song "Burning Love" from the original movie. Lilo refers to him as a "Hunkahunka bird of love".
- We learn that Hunkahunka's effects can cause people to love someone of the same gender, although this portrayal of homosexuality would be somewhat offensive to LGBT viewers.
- In his debut, Hunkahunka had dark purple feathers. However, in the show's intro, the episode "Snafu", and his later appearances, he had dark pink and maroon feathers on his body.
- Hunkahunka's pod color is white.
- Hunkahunka is described by the experiment computer screen as, "Experiment 323. Primary function: Makes the victim fall in love with the first person they see".
