Zir Zeal has the typical burrowing and respawning abilities of a Zombie enemy. However, when Zir Zeal burrows, he takes his sweet time to dig a huge 1500-length tunnel underground, exceeding the standing range of any cat. Consequentially, Zir Zeal tends to overshoot the blindspots of Long Distance Cats and will actually not pose an immediate threat to your backline. Of course, this also means that he may dig past any attackers that could immediately deal with him, so it's advised that you save the Cat Cannon to cancel his burrow or force him to the surface with a Holy Blast.
Seal-like being who came from the other world, hoping to become the subject of some rumors in the streets. Usually, he's laying on his back on a dirty river, eagerly awaiting someone to call out his name in a high-pitched voice.
