Continuity mistake: The number of pirates assaulting the hillside keeps changing. There are hundreds of them, then fewer than thirty, then hundreds again. In many scenes, in fact, there are far more pirates than could possibly fit aboard their one small ship. (01:55:30)

Revealing mistake: During Fritz's fight with the giant anaconda in the swamp, James MacArthur's stunt double becomes apparent by virtue of a bald spot showing on the back of his head. (01:10:30)

Revealing mistake: When Fritz is showing Roberta how to fire the rifle, several camera truck tire tracks can be seen on the beach behind them. (01:37:10)

Deliberate mistake: Fritz rescues the mud-trapped zebra and Roberta rides it across the island to the tree house, then again later in the race. Zebras, however, cannot be domesticated or ridden. To film these scenes, Disney & Co. painted a white horse with zebra stripes. (01:20:00 - 01:46:30)
