- Generally, whenever there's a nightmare sequence, the music and animation make it scarier than in the comic books.
- "The Seven Crystal Balls": The archeologists who found the mummy of Rascar Capac have been comatose since the Crystal Balls attack. Their skin has turned bluish (while it kept a normal color in the comic books) and they only wake up to horrifyingly scream in pain (while they only writhe about in the comic books).
- "Temple of the Sun" reveals the Inca tortured them with dolls.
- "Tintin in Tibet": The comic book doesn't quite convey how bone-chilling the Yeti's growls are in the cold night. The episode absolutely does, with echoes in the mountains. Then there's Tintin's encounter with it.
