Other mistake: There is a man and a woman who do the voices on the radios Leon listens to at Game Control. The man also does the voice for 530 AM at the airport, while the woman does the voice for the airport intercom, first noticeable when the White Team arrives at the airport. The woman then does the voice of the hotel operator, "Paging Mr. Player." These two are very busy indeed.
Other mistake: When Kit Mambo prepares to catch up with Renè Fromage, she first overtakes two guys (the raccoon and the bighorn sheep) on 'third and fourth positions' - as announced by Barbara Warbler, then she passes the sheep and the camel before she catches up with Renè. This would place her first competitors on positions five and four, instead of three and four.
Other mistake: As the people are going up the ramp to the Oyl's party, the man in the brown stops by the piling with a paper. As he bends over, there is a sound of the pelican pooping, and the man reacting to poop on his paper. The man and his paper are on one side of the piling, and the bird's tail is on the other. He couldn't have pooped on the paper unless he threw it.
