Toy Story 2

Woody prepares to go to cowboy camp with Andy, but when he accidentally rips Woody's right arm, Woody is put on a shelf. The next day, Woody finds Wheezy, a penguin squeaky toy, has been shelved for months due to a broken squeaker. When Andy's mother puts Wheezy in a yard sale, Woody rescues him, only to be stolen by a greedy toy collector, who takes him to his apartment. Buzz Lightyear and all of Andy's toys identify the thief from a commercial as Al McWhiggin, the owner of a toy store called Al's Toy Barn. Buzz, Hamm, Mr. Potato Head, Slinky Dog, and Rex all set out to rescue Woody.
At Al's apartment, Woody learns that he is a valuable collectable based on a 1950s[7] TV show called Woody's Roundup and is set to be sold to a toy museum in Tokyo, Japan. While the toys from the showâJessie, Woody's horse Bullseye, and Stinky Peteâare excited about going, Woody intents to return home since he is still one of Andy's toys. Jessie is upset because the museum is only interested in the collection if Woody is in it, meaning they will return to storage if he is absent from the collection. When his arm is torn off completely, Woody attempts to retrieve it and escape but is foiled by someone mysteriously turning on Al's television set. The next morning, a cleaner repairs his arm, and Woody learns that Jessie once belong to a child named Emily, who eventually outgrew her and gave her away. Stinky Pete warns him that the same fate awaits him when Andy grows up, whereas he will last forever in the museum. This convinces Woody to stay, now believing that all toys eventually get discarded by their owners.
Meanwhile, Buzz and the other toys eventually reach Al's Toy Barn. While searching for Woody, Buzz is imprisoned in a cardboard box by another Buzz Lightyear action figure with a utility belt, who thinks he is a real space ranger too. New Buzz joins the other toys, who mistake him for their Buzz. After discovering Al's plan, they arrive at his apartment while Old Buzz escapes and pursue them, accidentally freeing an Emperor Zurg toy, who immediately goes after him, intent on destroying him. After the toys find Woody, Old Buzz rejoins them and proves that he is Andy's Buzz, but Woody refuses to go home. Buzz reminds Woody of a toy's "true purpose" and how in a museum he will never be played with again. After seeing a boy play with him on the TV, Woody changes his mind and asks the Roundup toys to come with him, but Stinky Pete prevents their escape. Having foiled Woody's escape the previous night, Stinky Pete is determined to go to Japan because he was never sold to children, and allows Al to take the Roundup toys with him.
The gang follow Al, but are caught by Zurg, who battles New Buzz until Rex knocks him down Al's apartment. New Buzz then chooses to remain behind with an injured Zurg. Accompanied by three toy Aliens, Andy's toys steal a Pizza Planet delivery truck and follow Al to an airport, where they enter the baggage handling system and free Woody. Stinky Pete rips Woody's arm again while preventing his escape, but is stuffed into a little girl's Barbie backpack by Andy's toys to teach him a lesson. They free Bullseye, only for Jessie to end up on the plane bound for Japan. Assisted by Buzz and Bullseye, Woody frees Jessie and the toys find their way home.
When Andy returns from camp, he accepts Jessie, Bullseye, and the Aliens as his new toys, thinking his mother bought them, and repairs Woody's torn arm. Meanwhile, Al's business has suffered due to his failure to sell the Roundup toys. Woody tells Buzz that he is not worried about Andy discarding him because, when he does, they will still have each other for company. Wheezy's squeaker has been fixed and he performs a Frank Sinatra-style version of "You've Got a Friend in Me".
