Slick, A.K.A. Experiment 020, is an illegal genetic experiment created by Jumba Jookiba. He is designed to sell anything to anyone by using the tactics of a professional salesman. According to Jumba, 020 once sold the former's wife for an outrageous price. His one true place is selling for charity and fundraisers at Lilo's hula school. He is voiced by Jeff Bennett.
Lilo used him to get ahead in the chocolate bar selling contest/fundraiser, but Mertle took him. When Lilo took him back, Mertle took him back again. Lilo tried to take him back once more, but found out Mertle sold him to Reuben. Slick was rescued, but Lilo had to give up the contest by giving her last chocolate bar to Gantu as a swap for Slick. He then took part in fundraisers, following which he began working for charity, not profit. Slick was one of the experiments Lilo turned to for the capture of Ploot (505), but besides selling her an umbrella that she later used against Ploot, he didn't/couldn't help.
Slick is a fast-talking, Southern-accented salesman. He is generally very friendly and polite, tipping his hat every time he greets somebody, but is quite obsessive about selling stuff. He won't stop doing so until there is nothing left to sell, even selling himself to Mertle through a live auction. He is also very kind-hearted and courteous, and strongly supports his one true place in working for charity.
Despite being incredibly friendly, Slick can also be amazingly fierce. This was shown during the climactic battle in Leroy & Stitch. His initial facial expression after Stitch's pep talk was fearsome, and at one point during the battle, he had a Leroy clone running from him. Thus, he can easily turn from a friendly salesperson to a terrifying fighter, while still keeping his good intentions.
Slick is a fast-talking, pink doglike experiment with a resemblance to Jumba and Cannonball (520), but with a smaller face, a purple nose and two ebony-black eyes who wears a straw boater hat and bowtie, carries a cane, and speaks in the manner of a Southern-accented salesperson who never turns down a customer.
Slick can sell anything to anyone, even if they have no reason or wouldn't buy it otherwise, by using sympathy and slight exaggeration effects. He is capable of controlling his facial emotions and voice to persuade customers, and has a quick auctioneer-like speaking quality.
Slick is capable of speaking fluent English.
- Slick is very similar to Swamp Rat from 101 Dalmatians: The Series in that both are salesmen and both speak with a fast-talking Southern accent. The only difference is Swamp Rat is more of a con artist. Coincidentally, both Slick and Swamp Rat's voices are identical, and both even share the same voice actor, Jeff Bennett.
- Like Reuben, Slick is one of the very few known experiments that can speak English rather fluently.
- Slick's pod color is red.
- Slick is described by the experiment computer screen as, "Experiment 020. Primary function: Salesman".
