Calcifus Dweevil

The Calcifus Dweevil is a strange dweevil appearing in Pikmin: Dual Worlds. It can spit, from holes in its mandibles, a substance that covers what it hits in a strong, crystalline shell. The targets of this attack are mainly fellow dweevils, and Pikmin. Said shell only breaks after ten to thirty inclusive hits from Rock Pikmin, scaling up or down respectively for small and large enemies, but after sufficient damage, almost all of the crystal coating will be destroyed. If a Calcifus Dweevil happens to be near an enemy it gave a crystal shell that is now damaged, it will spit the substance onto their crystal shell, repairing it. The liquid crystal produced by Calcifus Dweevils contains microbes that instinctively distribute themselves evenly along the surface area of a living creature they come into contact with. This is done to ensure that the affected living beings are covered as evenly as possible before the substance hardens, the microbes dying in the process. Calcifus Dweevils have to charge up their spitting attack for four seconds each time they use it.

In the case of the Elder Foundation Dweevil, only a single leg's armor is destroyed, never the head's. When Spitball Dweevils and elemental dweevils are nearby, the Elder Foundation Dweevil becomes an extremely formidable and challenging opponent. When a Spitball Dweevil copies a Calcifus Dweevil, it turns light gray and spit balls of liquid crystal that effectively traps Pikmin in crystal, requiring Rock Pikmin to destroy. When repairing the leg armor of the Elder Foundation Dweevil, the crystal can become clumped around its legs and tapered feet.

Before damaging and destroying the crystal shell protecting an enemy that doesn't normally have one, kill any Calcifious Dweevils in their vicinity to prevent the battle against that enemy from lasting longer than is necessary. Calcifious Dweevils themselves can be killed as easily as other lesser dweevils, although the use of Rock Pikmin will be necessary if two Calcifious Dweevils had provided one another with a crystal coating.
