Tattle: This is a Monty Mole.
 * Mt. Rugged: Monty Moles are rock-throwing moles, big time mischief-makers. Ugh. They have kind of scary looking faces. They're pretty weak, though. Maybe they wear sunglasses because they have really sensitive eyes. Or maybe they're just hip.
 * Flower Fields: You remember Monty Moles from Mt. Rugged, don't you? They're vicious rock-throwers. They may look intimidating but they're not very strong.
