'IB' - Chapter Four
Soon all of Zim's tremors just seemed to halt. He pulled himself back up onto all fours, extending his head up with his neck still cocked at an awkward angle so he could see Dib's face. He parted his lips into the grin again, beginning to screech out in a single laughter with that eerie 'e' sound again.
The sight of that haunting grin seemed to paralyze the boy as he slowly let himself down to the floor, wrapping himself in a fetal position as he rocked himself very stiffly as if to comfort himself. Violent shivers also shook him as the cackle rung in his ears as they only intensified the dread he was already feeling.
