Logical Journey of the Zoombinis/YMMV


 * Excuse Plot
 * Nightmare Fuel: Much of the game, due to the eerie music and often surreal visuals, but especially the final leg through the mountain caves, and especially Bubblewonder Abyss, which has a dark atmosphere, creepy sound effects in the background, and the ability to vaporize any Zoombinis who take the wrong path through the maze (sure, you get them back, but that didn't make it any less scary!).
 * That One Level: Pretty much everything on Very, Very Hard. Hotel Dimensia and The Lion's Lair deserve special mention. The hotel has literally 100 rooms, meaning it's Trial and Error Gameplay here more than ever. And there's no clock to gauge how many chances you have left. If you can't figure out where each one goes in the time allotted, then too bad. As for The Lion's Lair... in this level, you'd get some sort of hint as to how to properly order the Zoombinis. Your hint here? You don't get one. This basically makes it like Hotel Dimensia with less chances to screw up; after your sixth wrong placement, the gate slams down and you can't take anybody else through.
 * Hotel Dimensia on Very Hard is worse. A random number of the 25 rooms are boarded up, meaning that if you place the first Zoombini in the wrong room, you've just irreversably screwed any chance you had of continuing with a full team without knowing it. At least on Very, Very Hard you can place a Zoombini in the right room without it being boarded up, even if there are 125 different rooms.
