The two super-annoying Rock-types who reside in EVERY SINGLE CAVE in their respective regions, which is made worse with their ability, Sturdy, which makes sure it requires at least 2 hits to knock the stupid thing out. Well, at least they have low Speed, so it's easy to run from them...
But, once you put them to use, they're actually somewhat useful (low Speed aside) so...
Who is more annoying?
Who is cooler?
Who is more useful?
Who's your favorite?
