Flint Beetle Family
Iridescent Flint Beetle/Pilli envelopens
The Iridescent Flint Beetle is a green Flint Beetle. It is virtually harmless and cannot be damaged by normal means, to damage it the captains must launch a Pikmin directly on its back. When doing so, the Iridescent Flint Beetle will release Nectar and Pellets that it normally stores in its stomach.
Stony Flint Beetle/Lithelytra sisyphons
The Stony Flint Beetle is a grey Flint Beetle with long legs and a strong carapace. It is usually seen pushing huge rocks with its muscular legs, if Captain Olimar or his Pikmin are in front of it, they can be crushed against a wall. The Pikmin can push the rock back if they are numberous enough which will eventually force the Stony Flint Beetle to flee.
Glint Beetle Family
Iridescent Glint Beetle/Pilli auricus
The Iridescent Glint Beetle is a golden Glint Beetle. They act in a very similar manner as the Iridescent Flint Beetle but they only live in caves and seems to be atracted to treasure to the point where they often swallow them. When the captains launch a Pikmin on their back they will spit out the treasure they swallowed and flee. Since they swallow treasures, the Prototype Detector will react to them.
Flint Bug Family
The Doodlebug is a Flint bug covered in dirt with small flies hovering around it that lives in caves. The Doodlebug will walk around at a pretty high speed and let poisonous cloud behind him, any Pikmin other than the White Pikmin will begin to die of poisoning if they step in it. If the captains launch a Pikmin on its back, it will release Nectar or a dose of spray.
