Revealing mistake: When Sheena gallops towards the prince's car, she is replaced by an obvious stunt double who not only does not resemble her but is a brunette, as opposed to blonde Sheena.
Continuity mistake: When the rhino crashes against the car, he dents its side with its horn and makes a hole. He walks back and rams again at the car, though now there's suddenly a second hole on the side.
Revealing mistake: When the prince's jeep crashes, he is replaced by a stiff dummy with a black bald head (or maybe a black helmet).
Continuity mistake: Sheena goes barefoot most of the movie but near the end when she's riding a zebra she's wearing a pair of sandals which disappear a few minutes later.
Revealing mistake: Sheena's arrow supposedly breaks the windshield and gets stuck on the driver's chest, but when the glass shatters, there's no arrow anywhere, neither breaking the glass nor stuck to his chest. It magically appears several shots later.
Continuity mistake: When the prince drives the jeep, his hair is short, as opposed to the POV shot where he has a really big afro.
Revealing mistake: Clearly a mannequin when Countess Zanda falls out of the helicopter.
Continuity mistake: Countess Zanda is Afro-American, but when she jumps out of the helicopter, her stunt double (or prop dummy used) is blonde and has white skin. A shot later, it swaps to a black-skinned dummy.
Continuity mistake: When Sheena shoots an arrow and breaks the jeep's windshield, there are bits of glass around the frame, but in the wide angle, there's just on the right side. This swaps back and forth.
Revealing mistake: The flamingos that attack the helicopter are blatantly fake, with their necks twisting around and puppet-like eyes.
Continuity mistake: The helicopter lands on the burning truck, but, shot later, it's 2 metres above. (01:17:26)
Visible crew/equipment: When the flamingos attack the helicopter, a crew member's hand is visible, moving one of them.
