It has long (755) range (longer than normal Lizard Cat, even longer than Radiant Aphrodite's actual range!!), can hit multiple units with an area attack (as opposed to the single-target, normal Lizard Cat), and attacks by shooting a (high-damage?) fireball. 3 Lizard Cats serve as the boss with regular streams of otters emerging from the enemy's base. These otters are the ones that will push through your defenses.
They are not TOO MUCH of a threat, but still be careful. When packed together, they are like mini Assassin Bears
