Rick and the squirrel turned to make their way back to the mirror, but as they approached, Rick saw a shadowy figure standing just behind the glass, its eyes fixed on him with an unnerving intensity. 'What's that?' Rick whispered to the squirrel, who stood up straight, its fur standing on end. 'That's the shadow,' the squirrel replied, 'it's been trying to pull people into the wrong world for years.' Rick felt a surge of fear, but the squirrel's calm demeanor reassured him, and together they approached the mirror, ready to face whatever lay ahead.
