Stupidity: The office Race is being held prisoner in has a thick wooden plank secured outside to prevent opening the door swinging to the outside, but the door was shown earlier opening to the inside. Furthermore, when Jonny rescues Race after lifting the plank, Race swings the door inside. Aside from the witch doctor guarding the shack, Race would not have been prevented from leaving.
Stupidity: While flying over the jungle in the Dragonfly, Dr. Quest uses the Dragonfly's speakers to tell the Po-Ho tribe he is their Air God and is angry for the tribe taking hostages. While he was at it, Quest should have ordered the Po-Ho's to release the hostages.
