Calla followed Maggie's motion, and peeked her head inside the open door after she did. Her eyebrows rose, and she mouthed the word,'wow'. That place had definitely seen better days. That was when she heard voices and saw someone's shadow. "Maggie," she whispered to get the other girls attention. When she had it, she pointed to the shadows. She stayed silent and still for a moment, her eyes glancing from the shadows, to Maggie. Finally, she signaled her to follow once again. 

Calla slowly pushed the door open m, the thing creaking a bit as she did. She immediately flinched and froze. After a few seconds, she continued, cautiously. It was then, that she released Maggie's hand, only to push herself up against a wall. She peeked around, and saw none other than her sister, Shaggy, and Scooby. She drew her eyebrows down in curiosity. How did they get here before they did? She quickly pushed the thought from her head when she saw a glimpse of Velma. The girl snuck up behind a suit of armor and snickered. Calla watched with interest on her face, her lips quirking up on one side. Velma then began to lift it's arms, and push it towards Daphne, who had her back turned to it. 

The arms suddenly touched her, and all three of them screamed in fright. Calla started laughing, not even bothering to hide herself.
