Bo rejects both Woody's proposal to go with him and become one of Bonnie's toys, since she has embraced her life as a "lost toy", as well as his call for help to search for Forky, though she ultimately agrees to accompany him to the latter, because she acquiesces "for old time's sake", and because Woody reminded her of how much she provided to Molly Davis as a toy when Molly was scared at night. To him though, she is still gentle, ladylike, and kindhearted. Bo reveals that her arm was broken off some time ago, but she managed to re-attach it to herself using scotch tape with his help. With the assistance of some lost toys and after being joined by Buzz, Bo leads the rescue mission for Forky, who has been captured by the film's main antagonist Gabby Gabby; however, Woody rushes out to free Forky in time to return to Bonnie, who is in the store, but this results in Bo's sheep being captured by Gabby Gabby and her toy henchmen. Though Bo manages to free her sheep, they are chipped in the process. Bo refuses a second attempt to free Forky, which causes Woody to angrily question her understanding of loyalty by saying that loyalty is something she wouldn't understand since she embraced herself as a "lost toy". After listening to Giggle badmouth Woody for his loyalty, Bo then realizes that loyalty is what she loves the most from Woody, and goes back to help and to reconcile with Woody.
