Sylvia blinked confusedly at the rattle, but she soon got the message as the crab waved its claw no. She put the knife away, and she heard Shortfang. Did she have anything shiny...? Her water ring wasn't very shiny, if anything when she first saw it, she dismissed as a normal ring before Mica pointed out that it was enchanted. There was gold, but she doubted the spirit would want gold. 

When it seemed as though she didn't have anything shiny, she remembered the hairpin in her hair. That counted as shiny...especially with the blue stone in it. She took the hairpin out of her hair, and held it in her hands. She felt her heart break as she looked at the pin in her hands. The thought of having to give this away for the stone hurt. She does her best to hold back tears, and silently offered it to the spirit.

...As precious as the hairpin her grandparents gave her is, she knows that she needs to continue on in order to get home. She can apologize to her grandparents when...if she gets back home.
