Continuity mistake: There's an electrical outlet on the wall below the window (aligned with the window shade's loop) in Sid's room near the Megadork poster, but when Sid throws Woody to the floor and raises the shade (before he scorches Woody's forehead with the magnifying glass), that outlet has vanished.

Continuity mistake: At the end of the first scene (skydiving) Bulk and Skull land in a construction site. A worker goes over to them and starts talking. At this time the guys still have their parachutes on. It then cuts to the worker and back to them and not only are the parachutes off, they are nowhere to be seen. (00:07:10)
Continuity mistake: In the scene where Kat is being introduced to her new classmates, Casper is seen tying the students' shoelaces together. This includes the snobby blonde sitting in front. But when the camera pans out, her feet are clearly too far apart for this, not like how they showed them while being tied.
Continuity mistake: When Omri receives his new skateboard as a birthday present the deck is red with two white stripes. For the rest of the film it is red with blue stripes.

Continuity mistake: Early in the movie when Thomas falls overboard, John Smith ties a rope around his waist (00:02:56) and jumps in after him. Thomas is very far away from the ship (00:03:12). But when the men pull John and Thomas up, John is holding on to the rope with one hand and the end is left dangling (00:03:36). One of the men who pulled them up then coils the rope with a mere two coils (00:03:48), not nearly long enough to have reached Thomas while he was overboard. In the same scene, when we are viewing the men pulling John and Thomas up from above (00:03:38) there is no extra rope at their feet as there should have been for such a long rope.
Continuity mistake: In the scene when Junior cuts the tree with his chainsaw, when he looks up to see how high it is, we can see it has branches. In the next scene when the tree falls on Scoutmaster Flimm, it doesn't have them at all and is cut straight at the top. (00:29:40 - 00:31:00)
