Tattle:
 * Spinning Tower: The Koopa Bros. have formed a tall Koopa tower! I'm not sure about this... They do a spinning attack with the whole gang piled high atop one another. Hit 'em with a Hammer or something to make 'em unstable. After that, any attack should knock 'em down. If you use an explosion, you can make 'em fall down at once. If you flip 'em over, the battle will nearly be ours! Beat 'em one by one!
 * Red: He's the Koopa Bros. leader.
 * Black: Black is pretty fashionable...
 * Yellow: Yellow reminds me of curry. Isn't that a weird thing to think of in the middle of a battle?
 * Green: He looks exactly the same as a normal Koopa Troopa.
 * Any Koopa Brother: He has a little bit of defense power, but you can turn him over by jumping on him, just like a normal Koopa Troopa. Let's flip him over quick! Otherwise, the Bros. may form a tower and do their famous spinning attack!
