You look at the choices. There's a pink piece of candy, toy vampire teeth in pink, blue and white, werewolf paws (you know because you can see that their is a thumb) in the same colors, more vampire teeth labeled Dracula, & a fang, which judging by their size & the theme of the choices so far, you figure it was supposed to have belonged to a werewolf.
"So what's the difference between the werewolf paw & the werewolf fang?" You ask him.
"One of them belonged to a pure-blood, the to a cursed. Which one's which, I can't tell you."
As he said pure-blood, it hit you who must be behind this.
"Hah! Robert must of put you up to this!" You exclaim. "And if I'm right, he would have the fang belong to the pure-blood & the paw to a cursed-blood. Hmm. The different colors of the same object isn't like him though. Someone else must have been in on it. usually I would say Gregg or Margie (She hates being called that by the way) but it doesn't seem like something either of them would do either. I know, it must have been Lisa & the different colors would refer to gender. OK, I'll play along. You can tell Robert that I took the fang." you pick up the fang and walked off.
you smile to yourself, you just outwitted Robert at his own game and walked off with the best hand. Though, come to think of it this seemed a little careless for one of Robert's tricks. He wouldn't put something that would point to him, unless he wanted you to know it was him, in their especially if he knew that person well and if that was the case he would have done it by himself and put an actual wolf fang in their & despite how real the fang you could look at the bottom and tell that it wasn't. you shrug it off thinking that he probably made it looke like this to confuse you. That's one thing you could credit Robert to do. When he sought out to do something, he followed through on it.
You continue to walk down the path unaware that you've grown taller and hairier.
