He and the other toys make amends and assist Buzz, Woody, and RC to make it to the moving van. Potato Head ordered for him to be tossed overboard (even though he felt sad about him being tossed overboard by the other toys). He is also guilty when he sees Woody was telling the truth after Mr. Woody desperately pleads for him to help, but all he can do is very sadly close the blinds of Andy's window, despite that Andy already misses Woody. When he and the other toys see Buzz's severed arm, Slinky looks devastated at what his friend seems to have done, and is convinced to now side with Mr. Potato Head snatches them as he tells the other toys as to if they have forgotten of what he did to Buzz. He catches the lights when Woody calls them from the window of Sid's room until a grumpy Mr. He is not happy about Woody's disappearance. He is also one of the toys who believes it was an accident when Woody knocks Buzz out the window. In the first film, Slinky is first seen coming out from under Andy's bed. Due to his older-looking appearance, he is seen to be very relaxed and calm but admits in the third film, 'I might be old, but I still got a spring in my step!'. This sometimes leads to him looking like a kiss-up towards Woody (something the toys make fun of, especially in the original film). He is nice, playful, likes to be pet, growls or barks at something he doesn't like, hides when afraid, and is very loyal to Woody, who is shown to reciprocate his feelings and is often seen petting him, comforting him, and playing checkers with him. Slinky acts very much so like an actual dog. 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. Eventually, after Woody not only attempted gruesome but formerly 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. 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.

Slinky was originally depicted as a long-suffering, abused right hand of Woody, and was also one of the most unpopular toys among Andy's collection. During rewrites, the character was changed to a dog, most likely to be more appealing. He is rescued from a toy collector and joins the main protagonists on their adventure before ending up at a kindergarten in the end. The earliest draft of Toy Story featured a slinky caterpillar who had never seen a child before.
