- Nightmare Freddy loves his personal space and hates being crowded
- Nightmare Freddy used to steal wires and eat them. This wasn't because he could eat, but bc when he bit them, they'd shock him, and bc of his high pain tolerance, it never hurt and just made him laugh. He doesn't do it anymore and he gets embarrassed whenever somebody brings it up
- Nightmare Freddy is one of the shortest but besides Nightmare, he's the oldest. That's why he acts more mature and annoyed than the others. This is also bc of the pattern of every Freddy character constantly stressing about keeping their family/animatronic friends safe.
