Tattle: These are the Hammer Bros. You've seen these punks before, haven't you? Be careful of that hammer! If it hits you, you'll get shrunk in a wink. When the Hammer Bros. get desperate, they'll hurl a ton of hammers, so watch it. These guys have been a pain for ages, so let's give 'em an old-fashioned whopping. As always, they're not to be underestimated.
