In the tiger pit Malcolm says: "Don'tmoveDon'tmoveDon'tmoveDon'tmove." Viewed from behind, his left arm hangs loose by his side. from the front, his left arm is across Dewey's chest.
In the bathroom, Reese opens the door. First he does not have his hand on the edge of the door. Then he does.
In the first aid room, Lois has a purse on her lap. Initially, we see no strap/handle. Then the strap/handle is over her arm.
When Reese is first surprised by the goat two people, one clutching a zebra doll, walk past in the background, twice.
Dewey holds a lollipop when he shouts "Tigers." He runs towards the tiger pit. When he gets to the fence he has no lollipop.
While Hal and Lois are discussing her old boyfriend Dennis, you can clearly see Reese in the background in the crowd. However, he is supposed to be fighting a goat and even makes a running-in entrance minutes later.
Correction: That's not Reese.
