Sir Seal (ゴマさま goma sama) is an enemy that appears in the Main Chapters and Stories of Legend Mode.
A classy seal who attacks quickly, endures attacks without flinching, and deals decent damage. It is recommended to use defensive cat units in tandem with fast-hitting units to defeat this enemy. Using a couple of Whale Cats (Evolution of Fish Cats) against this seal works too... for a while. After that, it's best to defend a platoon of Dragon Cats with a few blocking troops. Usually not a major threat in most levels, but there are exceptions such as Ancient One Piece and Angry Fighting.
It was known as "Sir Baby Seal" in the old English version.
