Slinky Dog

"Now Slinky here is as loyal as any dog you could want."

- Andy shows Slinky to Bonnie Slinky Dog (better known as Slinky and often called Slink) is Woody's dog and the secondary tritagonist in the Toy Story trilogy. Slinky, often referred to as "Slink," possesses wooden front and hind quarters, with a slinky as his middle. The character's name and basic appearance are modeled on a much older pull-toy dog, manufactured by James Industries (the Slinky company). When Toy Story was released theatrically in late 1995, the original toy had been out of production for at least five years. Thus, while toys of Woody, Buzz, and even a special edition Mr. Potato Head had been rushed to the market, company CEO Betty James had "mold problems" reworking the toy, and it was sometime later when Slinky Dog toys (now bearing the likeness of the Toy Story version) were shipped to stores.

Original concept
Originally, Slinky was depicted as a long-suffering, abused right hand of Woody, and was also one of the more unpopular toys among Andy's collection. According to Woody, the only reason Slinky wasn't hauled off to Goodwill, much less is actually played with by Andy, was because of Woody. Eventually, after Woody not only attempted murder against Buzz Lightyear, as well as being severely insulted by Woody when he hesitantly spoke up against what Woody did, he turned against his former master by telling the other toys to throw him out the window just as he had done to Buzz. This concept, as well as Slinky's overall demeanor, was changed after the infamous Black Friday Viewing of the film that resulted in it receiving an extensive redo.

Personality
Slinky is a nice, friendly, and playful dog. He is quite well-behaved compared with some of Andy's other toys. He shows faith in Woody (sometimes acting like his pet), and he'll do anything to help his friend out.

Toy Story
In the first film, Slinky is first seen coming out from under Andy's bed. He likes playing checkers with Woody. He is also one of the toys who believes it was an accident when Woody knocks Buzz out the window. He isn't happy about Woody's disappearance. He catches the lights when Woody calls them from the window of Sid's room until a grumpy Mr. Potato Head snatches them. When he and the other toys see Buzz's severed arm, Slinky looks devastated at what his friend seems to have done. Woody desperately pleads with him to help, but all he can do is close the curtains of Andy's window.

He is also guilty when he sees Woody telling the truth. He and the other toys make amends and assist Buzz, Woody and RC to make it to the moving van. He uses his stretching ability in an attempt to pull them into the van, but when RC's batteries rapidly drain, he becomes stretched to the breaking point. He loses his grip on Woody and gets sprung back into the moving van without them. He appears to be badly damaged, and the toys try and comfort him while he laments he should have held on longer. He looks ecstatic when Woody uses the rocket strapped to Buzz to return to them. His slink has been fixed at the end of the film, when the toys have been settled in Andy's new room.

Toy Story 2
In the second film, when Woody is looking for his hat to go to Cowboy Camp with Andy, it's Slinky who ends up finding Woody's hat. The bad news is that he got it from Buster, Andy's dog. After Al McWhiggin steals Woody, Slinky goes on the mission led by Buzz to rescue their valuable friend. The rescue squad uses Slinky's coil as a bungee cord to jump from Andy's house. Slinky also has to use two traffic cones (one on his head, another on his tail) when crossing the street due to his unique size and structure. At Al's Toy Barn, while searching in Al's office with a newer Buzz Lightyear action figure that the toys mistake for Andy's, Slinky encounters two Rock 'Em Sock 'Em Robots on Al's desk and asks them if they have seen "a cowboy doll with a bad arm" (referring to Woody), only to indirectly cause the two robots to fight. As Al enters the office, the New Buzz orders the toys to stow away in Al's bag, then they arrive at an apartment that houses Al's Penthouse. After entering the apartment through an air vent, they climb up an elevator shaft and arrive at the topmost floor with help from a rising elevator. When the toys break into the penthouse, Slinky and Bullseye have a growling match that Jessie tries to stop, but Slinky uses his coil to tie up Jessie and Bullseye. He then orders his allies to grab Woody and escape, but they are stopped by Andy's Buzz, who proves that he is the one that the toys recognize, to Slinky's relief. Slinky feels disappointed when Woody intends to stay with his Roundup gang to be put in a museum, and takes a possibly one last look at Woody before he leaves with the others, but brightens up when Woody declares that he is coming with them. After Al packs up Woody and the Roundup collection into his case and leaves the penthouse, the toys jump onto the elevator, and Buzz opens the emergency hatch on the elevator and uses Slinky to fish Woody out. Just as Slinky opens the case and grabs Woody's hands, the elevator reaches the lobby and Al steps out, causing Slinky to become stretched out, but Stinky Pete grabs Woody and pulls him back into the case, making Slinky accidentally release Woody and rebound. After the toys leave the apartment, they hijack a Pizza Planet delivery truck, and Slinky controls the pedals of the truck to chase Al to Tri-County International Airport. At the airport, Slinky follows Buzz, but his hind legs become stuck to one of the luggage handles, and is unable to follow Buzz as he becomes overstretched again. However, he is able to rejoin with the other toys as they stun Stinky Pete with flash cameras and finally capture him.

After the toys return home, Slinky is seen standing with Buster at the door, interpreting that Buster wants to get out of the room. Finally, Slinky is among an audience of toys who gather around to watch a fixed Wheezy sing "You've Got a Friend in Me."

Toy Story 3
In the third film, Slinky's voice gets a little deeper, and his eyebrows are slightly trimmer. He goes to Sunnyside Daycare with the others when they think that Andy no longer wants them and are put out on the sidewalk by Andy's mother (who is much older than she was in the previous films) as trash. Slinky is still very loyal to his friends, but is heartbroken when he believes he and the other toys are thrown out by Andy. At Sunnyside, Slinky, Hamm and Barbie shake hands with Stretch. Later, Slinky is seen being tangled up constantly by the young children, and is easily dispatched by Lotso and his gang, and imprisoned. Slinky is seen to be the happiest toy to see Woody return, and assists him in getting rid of the Monkey toy who monitors the security cameras. While the Monkey is overpowering Woody, Slinky grabs a piece of scotch tape, and the two succeed in taping up the Monkey. After reaching the dumpster, Slinky, being old but still has a spring in his step, manages to stretch himself across the open dumpster to the closed one so the toys can climb across to safety. Just as the toys are about to execute their leap to freedom, Lotso and his henchmen stop them, and Lotso kicks Slinky's paws, causing him to return to the chute.

After the toys end up at the Tri-County Landfill, and are pushed onto a garbage conveyor belt, Slinky is the first to be sucked up by a magnetic ceiling due to the metal slinky in his body. After the toys clear the shredders, they are left to die in an incinerator due to Lotso's betrayal, forcing Slinky to hold hands with Woody and Hamm when Buzz and the other toys held hands with one another, but are saved by the Aliens commandeering a giant claw at the last moment. Once outside the furnace, Slinky is the most vocal about wanting to get back at Lotso for leaving them to die, along with Hamm. But Woody tells Hamm and Slinky to forget it because Lotso isn't worth it.

When the toys return home, they use Slinky as a bungee cord to jump back up to the roof (the similar way Buzz's rescue party have done in the previous film when leaving). He tells Woody to have fun at college with Andy as he says his supposedly last farewell to his loyal friend. In the end, he and the other toys are eventually donated to Bonnie Anderson, a little girl who has taken Woody home earlier in the film.

During the end credits, when Dolly shows the toys the drawing Bonnie has made for each toy, Slinky says his catchphrase "Golly bob-howdy!" as he sees the one made of him (however, he doesn't say the catchphrase during the main events of the movie).

Finally, Slinky is last seen watching Buzz and Jessie perform a paso doble to "Hay Un Amigo En Mi," the Spanish version of "You've Got a Friend in Me."

Toy Story Land
Slinky Dog is the main feature of the Slinky Dog Zigzag Spin ride, a Himalaya style spinner ride in which guests are seated in Slinky's coils.

Toy Description
From Official Website:
 * "A dog is a man's best friend, and the saying holds true for the plastic variety as well. Slinky maintains a nearly unflagging faith in Woody, and the practical pup will go great lengths to help his friend."

Trivia

 * He had slightly large eyebrows in the first two films. However, his eyebrows are quite trim in the third film.
 * Slinky is made of wood with articulating legs and head, unlike the real life toy which is made of plastic and stands completely still.
 * At one point in Toy Story 2, Slinky says, "I may not be a smart dog, but I know what roadkill is." This is a reference to the quote "I'm not a smart man, but I know what love is" from the 1994 film Forrest Gump, which starred Tom Hanks, the voice of Woody, as the main character.
 * In the third film, Slinky's voice is a bit low pitch; in the previous films, his voice was a bit higher: this can be explained by the fact that Slinky isn't voiced by the same actor.
 * Slinky Dog is based on Slinky, a pull toy by James Industries, which was popular in the 1950s, 1960s and early 1970s. With the permission of James Industries, Slinky Dog was partially redesigned for the film by Pixar artist Bud Luckey to make him more appealing as an animated character.
 * In the first and second films, Slinky was voiced by the late Jim Varney, who died shortly after Toy Story 2 was released worldwide due to lung cancer in 2000, one decade before the third. In the third film, Blake Clark, Varney's new replacement, lent his voice to Slinky. Prior to Varney's death, he had been good friends with Clark.
 * He also appeared in Toy Story 3: The Video Game, and had his very own ranch called Slinky Corral (also, Blake Clark was available to reprise his role).
 * At one point in Toy Story 3, Hamm calls Slinky "Slinkykins."
 * His famous catchphrase: "Golly bob-howdy!" is a tribute to Jim Varney's most popular character, Ernest P. Worrell, whose trademark was this phrase.
 * Slinky didn't appear or was even mentioned in Toy Story of Terror. He must have been left behind at home during the events of that special.
