Flexing for Nougat

That's an... interesting costume you have on. Even though you're being nice and helping a sick child trick-or-treat this year, I'm afraid I'm going to have to ask you perform a trick for me!

Let's see... you look so strong and buff in that... costume... let's see you flex! Yes, go on now and flex for me, strong man/woman!

When and only when you flex, I'll give you some tasty Stormwind Nougat. It's a great Hallow's End treat.
