He likes playing checkers with Woody, usually choosing the red side.
Slinky is shown to be the most loyal to Woody and stands up for him when
Potato Head complains. Slinky is fascinated by Buzz, along with the
rest of the toys, but does not make fun of Woody when Buzz arrives like
the others do. When Woody knocks Buzz out of the window, Slinky is one
of the few toys who believes it was an accident. Later, when Andy
notices Woody is missing, he and Bo Peep are worried about him, in
contrast to the others, who are glad he's gone. Later, he attempts to
help when Woody throws a chain of Christmas lights from Sid's house to
Andy's, but Potato Head stops him. Even Slinky, though, appears to give
up on Woody when he pretends Buzz is with him but accidentally reveals
his broken arm. He is stretched almost to the point of breaking when
helping rescue Woody and Buzz on the moving truck, but is fixed by the
end of the film.
At the beginning of Toy Story 2,
Slinky is the one who finds Woody's hat, and joins Buzz, Hamm, Mr.
Potato Head and Rex on a mission to rescue Woody from Al McWhiggin of
Al's Toy Barn. His springy coil is used as a bungee cord when the toys
jump from the roof of Andy's house. When the toys break into Al's
apartment, Slinky uses his spring to hold Jessie and Bullseye back by
coiling them up so the toys can safely rescue Woody. After Al packs up
Woody and his Roundup gang and heads for the airport, Slinky, stretching
down from the elevator ceiling by Buzz, Hamm and Potato Head, reaches
for the case that contains Woody, and almost manages to save him, but is
thwarted by the Prospector. He goes to the airport with the others and
is able to rescue Woody, and returns home with the rest of the group. In
an outtake, he is seen petting his own hind section and talking to it.
In Toy Story 3,
Slinky has a smaller role compared to the previous two films[...]At Sunnyside
Daycare, he is seen being tangled up constantly by the young children,
and is easily dispatched by Lotso's gang and imprisoned. He is shown to
be the happiest toy to see Woody return, and assists him in subduing the
Monkey toy who monitors the security cameras. When the toys reach the
dumpster, Slinky stretches himself to create a bridge for the toys to
climb across to safety, although they are stopped by Lotso. When the
toys end up at the dump, Slinky is the first to be taken up by a
magnetic ceiling due to the metallic section of his body. When Lotso
betrays the toys and leaves them to be burned up in the incinerator,
Slinky is the first to follow Buzz in joining hands with his friends in
acceptance of their fate.
