“Grunkle Ford.” Mabel whined. She leaned over the side of her tank, dripping water onto the floorboards. “Where are Dipper and Stan? They said they’d be back with snacks for movie-noon hours ago.” Her Grunkle stopped grooming himself and looked at her, his barbed tongue hanging out of his mouth. He turned his gaze from her to the Mystery Shack brand clock that hanged over Mabel’s fish tank. It was true that his brother and nephew were overdue from their trip into town, however they were only thirty minutes late. The Sphinx-man shook his head.
