Ehh, you can punch 'em. I don't think I should be punching people if I can help it. [Even Amethyst has a line she doesn't cross. And apparently throwing a rock is free game, but punching isn't? It makes sense to her, okay.]

Either way, if throwing a rock doesn't do anything, punching probably won't. Maybe I can... scare 'em! [At that, Amethyst transforms into a very large and very toothy werewolf, growling and barking at the vendors.]
