It is recommended not to do this stage until you have a decent critter to take care of the Metal One Horn, but even something like Catasaurus will do. For the Le'noir, use Awakened Bahamut Cat, Sanada Yukimura and/or Maglev Cat paired with the default Cat Cannon to rush it if time is tight, or use any other anti-Black cat that has decent health and damage to slowly finish it. For the Chickful A, use Awakened Bahamut Cat, Maglev Cat and/or Fishman Cat. You may need to try this multiple times to get the max Timed Score Reward, which is 1,000,000 XP.
