Slappy- Headbutt

Instead of trying to get to the attic stairs, Kelly lurched at Slappy. She wrapped her hands around his head and tried to slam him to the floor.
But he was too strong for her. He ducked low and pulled his head free. Then he shot forward and gave her a hard head butt. I could hear the craaaack of the collision through the glass.
Kelly groaned and sank to the floor on her knees. Slappy came at her and swung his shoe hard in a vicious kick. She dodged to the right, and his foot sailed over her shoulder.
