Continuity mistake: When the LeBaron gets hit by the ambulance, we see that it comes to a stop about 10-15 feet from the corner. When the paramedics come out to help the woman in the car, it is now right at the corner. (00:38:50)
Continuity mistake: In the scene in which an ambulance wrecks the back of Judy and Peter's realtor, the license plate on the front of their car reads DBA-454. However, in the scene where Carl finds his car wrecked into a tree, when he backs out, his license plate also reads DBA-454. (00:38:50 - 00:52:35)
Continuity mistake: When the insect sits on the windowshield of the car Robin Williams says that the insects can't make a hole, they are safe, then the insect makes a hole, the car drives away creating havoc on the road because of extreme bad driving. The car stops, they get out, then there is no hole in the windowshield. (00:40:10)
Revealing mistake: When they are escaping from the giant mosquitos, Peter shifts the car into 1st gear, not drive. (00:40:40)
Continuity mistake: In the kitchen Alan opens the fridge and the monkey runs out. Judy is standing there and both her plaits are hanging behind her. In the next shot they are both hanging over her right shoulder. (00:41:25)
Continuity mistake: When Alan explains who he is to Sarah, she peers out through a door that's only open a crack. But when the shot cuts to Alan, his entire head and practically both his shoulders are visible through the door. When it switches back to Sarah, Alan appears to be at least two feet away (since he's totally out of the shot) and the door is still open the crack of a few inches. (00:47:20)
Visible crew/equipment: In the scene when the pods and vines start growing all over the lounge, there is one shot of a green vine crawling towards a carpet, and then slithering under. Watch closely, near the carpet, and you can see the wire attached to, and controlling the vine, because the light shines on it, exposing it rather well for a second. (00:48:40)
Continuity mistake: The licence plate on Carl's car is "G2298" but after finding the car which the monkeys had smashed into a tree, as he reverses, the plate is "DBA 454." (00:50:30)
Continuity mistake: When Van Pelt comes out of Jumanji, he starts shooting at Alan. Alan then runs through the brown doors, and Van Pelt shoots, misses, and blows a large hole into the door. Yet when they all return to the room, the hole in the door is smaller. (00:53:20 - 00:55:25)
Audio problem: When Van Pelt is chasing Alan outside the house, he turns to shoot at Carl the cop. If you count the shots heard fired, there is one more hole than bullets heard. (00:56:15)
Continuity mistake: When the hunter fires at the cop (with his old gun) he fires once and the cop ducks behind the car. We see three bullet holes in the car when there should only be one. (00:56:15)
Continuity mistake: After the stampede, Alan runs off, then so do Sarah and Peter, and then the phone rings, so Judy answers it. Down the hallway you can see a chandelier, barely swinging. Yet when it cuts to Judy answering the phone, the chandelier is swinging much more violently. (00:57:35)
Continuity mistake: When Alan is trying to get Jumanji back from the pelican, he grabs a fish from the water, and his sleeve becomes soaking wet. In the next shot his sleeve is bone dry. (00:59:05)
Continuity mistake: Throughout the day the sun seems to go from an afternoon dusk sun when Van Pelt returns to the house, to an overhead sun during the stampede in town. It also goes from overcast and cloudy to clear cloudless sky with sun from shot to shot. (01:02:30)
Continuity mistake: When the monkeys are in town looking at the electronics store TVs, there is no sun in front of the store. Once the angle changes to a front view, the sun is now shining where the monkeys were standing in shadow before. (01:05:15)
Continuity mistake: When Sarah, Judy and Peter are in the store, where the riot is going on, they spot the Jumanji Board Game sitting on the till counter. To the right of the till is a very large "Sand and Water Activity Table" box. In one shot the box it facing so you can see the upper part/top of the box. It then cuts, and the box has mysteriously rotated 180°, so that you can now see the lower part/bottom of the box! In the same shots, there is a trolley by the till, with some items and a box in it. Cut back to the trolley and there's now two boxes in it! It then cuts, and the box is back to it's original position, and the box in the trolley disappears! If you look more closely, the entire shelf unit behind the counter is completely different!!! (01:05:55)
Continuity mistake: During the rampage through town, the driver of a red Ford parks and then runs out in panic. In one shot, the license plate number is AZP-281. In the next shot, it is SLP-281. (01:07:16)
Continuity mistake: In the store, Hunter Van Pelt shoots his gun and hits the side of the tyre shelf, making a nick/hole in the red paint. The size and shape of the nick/hole changes between the two closeups of it, before the chain snaps and releases the tyres. (01:09:25)
Continuity mistake: When Van Pelt shoots the tire shelf in the store, the attached red wood triangle support is actually different between shots - note paint and dings. Furthermore, dirt marks on the tires appear, and two of the slotted heads of the screws, that are screwed into the anchor eye plate, are turned facing opposite directions (before it breaks). (01:09:25)
Continuity mistake: While Alan is handcuffing Carl to the police car, the sky is clear and the sun is shining from the left (driver's) side of the car (indicated by strong shadows). As Alan is tossing the cuff keys away, the camera cuts to a view of the back of the police car which was shot on an overcast day, with the shadows very muted, and the sun coming from the car's right side. The view cuts again as Alan turns to run back to the police car, and we're back in bright sunlight from the left side. A couple shots later, as the car is reversing into the quick U-turn, the sun is shining from the car's right side again, this time with strong shadows. (01:09:30)
Answer: Since the barb was poisonous, she was dying. This is seen when she begins looking pale and a few seconds later she isn't moving. Finishing the game was the only way to save her life.
