Battleground
Croco and Squire Rel spawn at a moderate rate throughout the battle.

Gory Junior will spawn as a boss when the enemy base is attacked.
Strategy
While harder than the previous stage by a small margin, this stage can still be beaten using simple Cow Cat spam if you have a decent amount of Treasure.
