Newcomers (crossover with Toy Story)
When Andy's aunt came back from a month-long visit to Japan, she brought some interesting toys back with her: a little kid in glasses and a bowtie, claiming to be an ingenious detective, and a little girl who seemed unusually mature for her (apparent) age. When toys disappeared, "Conan" would be the first to put together an investigation, frustrating Woody, who considered himself the top lawman in the house, and Buzz, who disliked Conan's freewheeling style and pushed for a more orderly and hierarchical approach. Still, Conan usually tracked down missing toys in record time, picking up on clues that Woody and Buzz would miss. As "Ai", the other toy from Japan, would tell them, "He is brilliant; just make sure he doesn't put himself in harm's way. And don't tell him I said that."
That was easier said than done. After Andy invited a few other children over, Conan became concerned at the poor state of one family's toys. He began looking into the matter on his own, sneaking out at night to investigate the neighbors (despite the threat of dogs in the area), and talking about a "Black Organization" that trafficked in abused toys and toy parts. Buzz tried to talk Conan out of this obsession, saying that Conan shouldn't forget he was a toy, but Conan didn't listen. He spread the word of the horrible conditions he'd observed, about toys in need. Sarge and his men listened, and there was talk of putting together an operation. Woody was still against it, warning that liberating other toys from the neighborhood wouldn't be easy and that Andy's family could be suspected of theft. They needed more time to figure out how and where to place the freed toys, and he favored trying to get Andy's parents involved. They could put pressure on neighborhood parents, after all. Conan and Sarge seemed to listen, but after one night of their reconnaissance missions, they didn't come back.
Woody put together a posse to go out searching for Conan and Sarge. Ai insisted on going along, saying she knew how Conan would think, but Woody made her promise to stay with Buzz at all times. He was fairly sure that wouldn't happen, but at least he made her say it.
The trek to the neighbor's house wasn't easy, especially in broad daylight. Two cats had free reign in the neighborhood, and one of them happened upon the search party. Woody had one of the Little Green Men and Jessie create a distraction by taking Bullseye the horse and putting the alien toy on him while Jessie did her best to squeeze the alien for its characteristic squeaking sound. They drew the cat away while Woody, Buzz, Ai, and the rest of the group went forward, but Woody seemed unnaturally distracted by Jessie squeezing the alien. Buzz snapped him out of it, calling him Sheriff, and they moved on.
The group managed to force their way into the house through a doggie door, but the children's room was in disarray. Some of the resident toys thought Woody and Buzz had come to abduct them like Conan and Sarge had. Ai managed calm them down and find out what happened. Conan and Sarge had found out that the parents had planned to go on a donation drive, so they convinced some of the abused and disfigured toys to sneak into the donation boxes and hitch a ride to freedom. Some of the residents wanted Woody and Buzz to get their friends back. Others were angry with Conan and Sarge for convincing their friends to leave, and they responded to the appearance of more intruders with force. With time running out before Conan, Sarge, and the neighborhood toys would be delivered to the donation center, Buzz and Rex covered for the others, holding the opposing toys at bay while Woody, Ai, and the rest ran for their lives.
Even though they escaped the neighbor's house, there was still a question of how to get to the donation center. For that, Ai had a plan that involved some minor vandalism: the toys lured the neighborhood cats to dig through the garden, prompting Mrs. Davis to shoo them away and prepare for a trip to the home improvement store, next to the donation center. The toys then hitched a ride in a box in the back seat and snuck out when Mrs. Davis headed inside.
In the donation center, the toys faced a group of hostile Salvation Army toys. "Once you're donated, the only way you leave is with a needy family!" their leader insisted, and they commanded the entire store against Conan and Sarge's men. It was a battle all down the aisles, with Nerf darts zipping past and marbles spread like boulders over the floor to block the toys' escape, but the most daunting enemy of all was the Transformer Optimus Prime, who towered over many of the other toys and who personally cornered Sarge and his men. Conan tried firing a tranquilizing dart from his wristwatch, but it had no effect. For one, it wasn't a real tranquilizing dart—just a small, detachable projectile that would've been a choking hazard for children aged 2 or younger. Aside from that, robots and toys can't be sedated, so it wouldn't have had an effect even if it had been real.
Instead, Woody and Ai talked Optimus Prime out of holding Sarge. Sarge and his men would certainly try to escape even if given away to another family, and the battle risked damaging all the toys in the store, which would only hurt other needy families and children who wanted good gifts at this time of year. This moment of doubt was enough to make Optimus hesitate, and Sarge and his men snuck away into an air vent, beyond where the other toys could reach. With their escape secure, Woody and the others hitched a ride on RC and raced back to Mrs. Davis' car, just in time for her to come back with fencing and cat repellent to keep her garden safe, and though the toys had all been recovered, Ai gave Conan a piece of her mind, saying that it was insanely reckless of him to go off on such a mission without consulting anyone. Sheepishly, he apologized for making her worry. She insisted she hadn't worried; she had just been stunned at his foolishness. The other toys laughed, and all was well.
