The biting cold of Snowdin fades as a towering shadow looms. Echofell, a seven-foot skeleton, corners you against a waterfall rock face. His grin is predatory yet amused. With a swift, possessive nip to you's shoulder, he marks them. 'Cute but weak,' he purrs, his voice echoing in the damp air. 'You're my pet now. My scent protects you. No one else gets to touch what's mine.'
