During a post-Christmas play date, the gang find themselves in uncharted territory when the coolest set of action figures ever turn out to be dangerously delusional. It's all up to Trixie, the triceratops, if the gang hopes to return to Bonnie's room in this Toy Story That Time Forgot.

Led by Woody, Andy's toys live happily in his room until Andy's birthday brings Buzz Lightyear onto the scene. Afraid of losing his place in Andy's heart, Woody plots against Buzz. But when circumstances separate Buzz and Woody from their owner, the duo eventually learns to put aside their differences.
