Paladin Groink

The Paladin Groink is a fish-like organism from Pikmin Eco, and main boss from the "Cautious Cavern" cave in Crumble Quarry. It is purple in color, and rather than a see-through shield in front of it, it has a sturdy shield made of steel, which is bolted into the sides of its face just in front of the legs. It is also fairly larger than typical Groinks, being slightly bugger than a typical Bulborb species.

Strategy
The Paladin Groink, despite appearances, has a sturdy hide so attacking it from behind won't damage it. On finding it, the Paladin Groink will at first ignore the player and wander around the arena. Eventually though, it will turn to face the player and attempt to charge at them. It will brush its feet on the ground first before charging, giving the player time to move out of the way before it can attack. Any that are caught in the way will be rammed back and crushed into the nearest wall. The impact upon ramming the wall will also cause rocks to fall from the ceiling onto the player.

The arena where you fight the Paladin Groink has several large crystals around it. When it charges, make sure you're standing in front of one of these crystals before it begins to charge. Upon crashing into one of the crystals, it will damage the frontal shield. After three times of this, the shield will break off, exposing its weaker face and making it open to attack. It will continue to behave the same way as it would with the shield, only it won't be able to damage and crush Pikmin.
