Nightmare Stitch is an unofficial antagonist in Five Nights at Treasure Island.
Stitch looks similar to Stitch, only he has spikes where his ears should be and no eyes, as well as a hanging jaw.
He starts moving on Night 2 (Nightmare Before Disney). When active, he can say the following things:
- "I'm not sorry."
- "If only they didn't know."
- "How could you have done this?"
