The Mandiblard Family consists of eight known species, two of which are known to demonstrate a degree of sexual dimorphism not uncommon to insects. As a whole, they have little vitality and are not especially dangerous, but like the Cloaking Burrow-nit, they are infamous for tearing apart nearby stick bridges which Pikmin have built. Due to their general inability to present any danger, these enemies are usually found in groups of 3 or more, and are always buried in the ground, appearing only when a Captain or Pikmin approaches close by.
Male Sheargrubs[]
Male Sheargrubs have a dark purple shell and large mandibles. They are capable of attacking Olimar and the Pikmin, but are not a serious threat, as they can only eat one Pikmin at a time. In Pikmin, when a Male Sheargrub has a Pikmin in its mouth, it is invulnerable to most attacks and can only be defeated either after it has eaten the Pikmin, or if a Pikmin is thrown directly onto its back. This was fixed in Pikmin 2, allowing players to kill them by any method, even if they have a Pikmin in their jaws.
Female Sheargrubs[]
Female Sheargrubs are a much lighter color than the males and have significantly smaller mandibles, making them unable to cause direct harm to you or your Pikmin, though they are still a menace for bridges. They can be ignored in most situations, perhaps only useful as a means of easy-access Nectar, which they will produce if killed while petrified.
They also lack the exoskeleton their male counterparts carry around with them.
Swarming Sheargrub[]
The Swarming Sheargrub is a large Mandiblard that is somewhat similar to the Female Sheargrub in appearance, besides size and color. They are known to follow Pikmin from a distance, and can be a distraction to your Pikmin swarm. They can grow in size after consuming a dose of Nectar, and can weigh down objects.
Sporegrub[]
Sporegrubs are tiny, poisonous species of Mandiblard found in the Ravaged Rustworks and Lushlife Murk of Hey! Pikmin. A mutated variety of Sheargrub, it is able to release a toxic gas on its body as protection and to guard its territory. One Pikmin can kill a Sporegrub, but if missed it'll release its cloud.
Speargrub[]
Speargrubs are a spiked species of Mandiblard found mainly in the Sparkling Labyrinth. Unlike the other Mandiblard, Speargrubs are unkillable, but are able to freeze for a few seconds if struck by a Rock Pikmin.
Shearblug[]
Shearblugs are semi-aquatic Mandiblards found in the Verdant Waterfront. like the Speargrub, it has spikes for defense but are exceptionally larger in size, and is able to curl up into a ball to defend itself.
Shearwigs[]
Shearwigs are enemies that appear in all four Pikmin games. The females of this species are never seen, as they spend nearly their entire life underground. The males have a dark green shell, sporting simple wings and large, sickle-shaped mandibles. They are slightly more aggressive than Male Sheargrubs and will fly to safety when their health descends to the yellow zone; up in the air, they regain health. One well-aimed Pikmin will bring a flying Shearwig down for good. Both Sheargrubs and Shearwigs will drown quickly in water, so luring them into a pool is an alternative strategy if you're short of Pikmin. Shearwigs deal the most damage to captains out of any enemy in Pikmin 2.
Queen Shearwig[]
The Queen Shearwig is the hive mind of Shearwigs, and the fifth boss in Hey! Pikmin. The queen is a much larger version of Shearwig, pink, and mandibles resembling a drill. She is able to command a troop of Shearwigs to protect her from threats and attack prey for her.
