Fade walks towards you, a pouch of pebbles in jaw, along with some- bones?!
"What are those?" You ask, curious.
"Knucklebones-" Comes the reply.
"If you catch me, I might drop some of them. (in this forum, NOT flea market) The ones I drop will go to the first one to shout out, CLAIM! Of course, you'll have to drop a pebble for me."
"I will drop them at random times, there are 4 or 5 knucklebones I might drop. Good luck!"
