Ripples Island is the second stage in Castle of Fish.
During the Battle
St. Pigge the 2nd will spawn at a quick rate when the enemy's base begins to take damage.
Be wary when hitting the base; a flurry of St. Pigge the 2nd will appear.
A standard slew of anti-red and normal cats will work fine. Brave and Whale cats will do good damage to the St. Piggies. If available, Paris and Swordsman Cat will do great damage to the piggies.
