Do a flex emote at Innkeeper Gryshka, and in exchange you'll receive Orgrimmar Nougat!
Flex for Innkeeper Gryshka: 0/1
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 Orgrimmar Nougat. It's a great Hallow's End treat.
