Chapter 9: When the elephant carrying Tim crashes the gate, Tim is a recognizable dummy filled with straw.
Chapter 10: In one shot, Lazarre is clean shaven, in the rest of the chapter, he sports a full beard.
In Chapter 8, Tim gets knocked into the river head first, but the slightly obvious stunt double lands in the water feet first.
A few of the closing placards seem to be made at a different time. In any case, the placard currently ending Chapter 6 tells audiences not to miss the next chapter "King of the Gorillas." The title card of Chapter 7, however, titles the installment as "The King of the Gorillas," which is slightly different. The difference can also be seen in the spelling of "theater," where original footage spells it "theatre."
In Chapter 7, Lora leaves Tim with his father to look for water (exiting left near the camera on the screen). She passes a cave opening where a gorilla soon enters and heads towards Tim. When Tim looks up and sees the gorilla bearing down on him, the ape approaches from a completely different direction than Lora's exit (far right on the screen).
In Chapter 10, horses are terrified by the approach of an anteater, a native of Central and South America, not of Africa.
Seen in Chapter 10: The setting is Africa, but Bolo is an Asian elephant rather than an African elephant.
The second panel in the cartoon recap that starts Charter 5 shows the scene where Tim's caught in a tree snare by Jules, but the caption below describes Prof. Tyler captured by Spider Webb's outlaws, which was a different scene altogether.
Having filled his hat with water to aid the injured mahout (with Bolo the elephant subsequently refilling it), Tim puts his hat back on without shaking any water from it, apparently completely dry precisely one minute and a half after being full. Such awesome evaporation. That's not Africa hot, that's planet Mercury hot.
The Jungle Cruiser has been running about through at least ten of the twelve episodes without ever refueling. In Chapter 12, Spider finally mentions getting it refueled, but where is fuel kept or located? Certainly it would seem dangerous and laborious to crisscross the swamp and its quicksand hazards to tote fuel containers. And where would one find a service station in Africa for a tank?
In Chapter: 10, In the cave Tim and Lazarre can hear the gun shots of Spider Web's gang, but Spider and his gang don't hear Lazarre shooting at the gorilla in the cave.
In Chapter 2, Tim meets a white man leading an ivory safari who never introduces himself. Almost four minutes into Chapter Three, Tim asks, "Can you hear me, Mr. Spencer?" suddenly knowing his name.
In Chapter 4, Sgt. Gates sends Patrolman Berry back to the Ivory Patrol base with Tim's horse. Hearing shots in Chapter 5, Berry rushes to Gates' side. The two men then return to base but arrive without Tim's horse.
In Chapter Eleven and according to dialogue, only Tim knows that the elephants' graveyard lays past a smoking passage, yet that's exactly where Spider, who never had this knowledge, stops to gather tusks. Contrarily, The Ivory Patrol group doesn't know where to look the closer they get to it.
In Chapter 9, With Tim inches away from at least one crocodile, Lora shrieks and throws down a rope end to him, holding the other end so the boy, weighted with water, can grab it and climb up to safety. With Tim practically in their grasp, one wonders why the crocs delayed their attack or how Lora, approximately the same size as Tim, could support his weight as he climbed up, neither of them out of breath once Tim got back aboard.
In Chapter 8, Tim looks across the deck and sees Spider. Tim scales the boat to jump Spider from behind on the deck above. Not only must Tim have x-ray super powers but light refracting super powers as well to look straight ahead and see Spider on the deck above and through the floor boards. Either that or Tim has a precognitive ability, because when he sees Spider, Spider has floorboards over his head, so Tim climbs the boat to be able to jump Spider from behind just after Spider teleports to the open deck above.
In Chapter 3, Tim, Lora and members of her safari take refuge in a cave, only to find that it's a den of lions - all male. Lions live mainly on open planes, not in caves (nor deserts nor rainforest jungles), and usually live one male to a pride (surrounded by females who do all the hunting). In nature, a lion's den might constitute a female desiring privacy while giving birth. Grown males gathering in groups is not a trait of lions.
It's Tim's kindheartedness that wins over human and animal friends alike, but in Chapter 12, Bolo gets shot at from behind, yet never once does Tim allow his elephant friend to avoid fire or take cover, nor does he check his friend's derriere for bullet wounds and blood.
