Seaweed Shallows is the seventh stage in Swimming Cats.
Be careful, as every enemy in this level but Doge Dark has a 400% strength magnification. Use long ranged units such as Dragon Cat, Nerd/Hacker Cat or Nekoluga/Unknown Cat. If you have Nekoluga, use him in his evolved form to push back the Teacher Bears so you can attack the enemy base. If you have Bahamut Cat, use him to deal heavy damage to the Teacher Bears and Doge Darks, but be wary of Teacher Bears' range.
