Much like the other Balls from the event, it's really weak by itself, but really tough in groups particularly when buffed. By nature of having the Metal Trait and one knockback, it is the tankiest of the Balls, but has slow speed. Fast attacking units such as Crazed Cow Cat or Rocker Cat can chip its health pretty fast, and any Critical Hit will defeat it no matter what due its pathetic 20 health, so units like Catyphoon are perfect for defeating them. You can also use Curry Cat or Lollycat to slow it down, due to its abysmal range of 100.
