Zroco is the second variant of Croco, that is Zombie enemy. It has approximately the stats of a 500% Kroxo, or a 20,000% Croco, as well as having the abilities unique to Zombie enemies along with a 30% chance to weaken cat's attack power by 50%.
When Zroco burrows, the time during which it is underground is surprisingly low compared to other Zombies. It has rather high DPS for a peon enemy, too.
I am hungry and crocodile that died. On the way to cross the Mitsunogawa river, my physical strength was exhausted and I returned to this world in a half way shape. Recently I often get mistaken for dumbbells.
30% chance to weaken Cat Units' attack power by 50% for 150f 5 seconds;
100% chance to revive at 100% HP after dying for 480f 16 seconds (1 time);
100% chance to burrow underground for 375 when a Cat enters its range (1 time).
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
Zroco's tongue is hanging out despite the fact that real crocodiles can't do that.
In the EN version, River Styx can be found in its description, which is where you fight the first deadly boss, Hannya. Furthermore, he and Zollow are the only Zombie enemies which reference it, in the game.
The River Styx is also a famous river in the Greek underworld, bridging the underworld from the rest of the world.
