Continuity mistake: When the army men parachute down from upstairs, they disappear before the next scene. You see them when they land, but when the other soldiers come down they just aren't there anymore. (00:09:40)
Continuity mistake: When Buzz drops into the van through the sunroof (at the gas station) he has a dead fly stuck to his helmet shield. Woody attempts to pull it off and clean the glass, but doesn't finish the job as there is still some goo on the glass where the fly was. On the following shot the glass is completely clean. (00:30:14)
Continuity mistake: In the beginning of the movie, Andy puts Woody on RC and drives RC into a cardboard building. Later, when Woody says the coast is clear and everyone comes alive, RC is seen coming out of the closet but the last place he was left was by that box in the room. (00:02:00 - 00:03:45)
Continuity mistake: When Andy goes to his room to get Molly, he lowers the side of her crib in order to get her out, picks her up, and walks out of the room. In the next shot of his room, the crib side is back up. (00:03:13)
Factual error: When the soldiers are asked to find out what gifts Andy is getting at his birthday party, the set out down stairs with half of a baby monitor. Well, any parent who owns one knows that there are 2 pieces to a baby monitor. One half (the larger half) is the receiving end (that takes in the noises) and a smaller half which is the transmitting part (the half that sends out the noises). The half that the soldiers take downstairs to talk through is the wrong half. They take the half that the noise comes OUT of. So, really, they should NOT be able to speak into this part - in real life, they'd hear what was happening up in Andy's room. (00:09:18)
Revealing mistake: After the opening credits when Woody is on Andy's bed, right after Woody opens his eyes and lifts himself up, his left hand passes through his face.
Continuity mistake: When Woody opens the back door on the moving van, the ramp handle is black. But when Rocky Gibraltar uses it, it is red.
Continuity mistake: When Sid runs out of his room with Buzz, the chair's in front of the dresser smack between the bed and wall, but when Babyface knocks out the morse code on the bed frame the chair should be seen but has vanished, and then it reappears where it should be, right beside the bed.
Continuity mistake: After Buzz knocks over the tool box onto Woody, in the overhead shot from behind Buzz as he looks down at the floor and also the closeup of the toolbox, the dumbbell's between the chair and bed, but when Sid grabs Buzz and runs off the dumbbell's moved to the other side of the chair, beside the wall and dresser.
Continuity mistake: When Sid opens the box from the fireworks company and takes out the rocket, he pushes the large corrugated box towards the window, but when Sid puts the milk crate with Woody onto the table that large box has vanished.
Continuity mistake: When Andy's toys see Woody holding Buzz's severed arm they abandon him, and Slink drops the window blinds while Woody's leaning out Sid's window that's still open, but when Woody turns around to see Sid's mutant toys start working on Buzz, Woody jumps off the table and suddenly that window is closed behind him.
Continuity mistake: When Molly is playing with Mr. Potato Head, she knocks all of the pieces off his head, except one arm. The next time Mr. Potato Head is seen, he has lips, one eye, one eyebrow and both hands. (00:03:19)
Continuity mistake: Toward the end of the movie when Woody opens the moving van door and is hanging on it you can see in the background Scud trying to get Buzz from underneath the car, but right after Woody spots the box he needs to look in we are shown a scene of Scud struggling with Buzz who is at this point thrown under the car. (01:08:55)
Continuity mistake: When the toy soldiers get stepped on, the mom sweeps them with her foot to the right of the door. So when they are active again and go the left, they should go by the door right away. Instead they are to the right of the potted plant. (00:10:50)
Other mistake: When Andy's friends show up all of the Caucasian boys have Andy's face and hair. Most surely due to the limited technology available then, but weird nevertheless.
Other mistake: After throwing Woody to the floor, Sid raises the window shade and tries to burn a hole in Woody's head by using a magnifying glass to focus the sunlight. Sid is leaning over Woody with his back toward the window and yet he does not cast a shadow on Woody. In addition, the position of Sid's body would block the sun's rays from hitting the magnifying glass but the close-up shows the narrow beam of light hitting Woody's head.
Continuity mistake: At 09:21 on BluRay disc, is the scene where Woody is instructing the army man to go downstairs. You can see in his left hand there is a set of binoculars and in his right hand is a pistol. In the very next shot (at 09:26) you can see the binoculars in his left hand, but the pistol has disappeared from his right hand, enabling him to salute Woody. A few shots later (09:33) we get a good look at the army man. The pistol is still missing. We also get a look at the holster, which is empty. There was no time for the army man to put the pistol in the holster between shots, and it would technically be moulded to his hand anyway. (00:09:20)
Continuity mistake: When RC bumps into the corkboard, the pins fall off and stick into the desk. When the globe starts rolling towards Buzz, the pins are gone. (00:27:00)
Continuity mistake: When Woody and Buzz run for the Pizza Planet doors under cover of Pizza Planet cups and burger dishes, Buzz says, "Hurry Sheriff, the airlock is closing!" Just after he says that, the camera changes view to inside Pizza Planet, and the distance that they've run changes instantly. (00:33:22)
Deliberate mistake: Sid burns a hole into Woody's forehead in the middle of the film, but by the final scene (as the toys are waiting to hear what Andy has gotten for Christmas), the burn hole is completely gone. [Disney takes the attitude that violence is okay in their movies as long as the signs of it disappear by the end. Still a mistake but that's the reason.] (00:43:35)
Answer: Baby face taps RR TOYS COME OUT. Telling the other toys to come out from hiding. Pixar stated this in their Toy Story character overview.
But why "RR"?
"RR" is shorthand for "Message Received." Babyface is telling Woody that he understands Woody's problem and then taps out to the other toys to come out.
