Breadbug family
The Breadbug family is a family of species in the Pikmin games that steal items and corpses, or mimic young Grub-dogs. The most famous member of this family is the Dwarf Red Bulborb. The name Breadbug may be derived from the fact that they resemble bread.
Breadbug
Breadbugs, found in both Pikmin games, are the beasts after which the Breadbug family is named. They are unable to cause harm to Pikmin directly, though one can do so by pulling objects away into its dwelling. If any Pikmin are carrying an object while it is sucked underground in this manner, they will die. The beast has a large amount of hard blubber, making it nearly immune to most attacks. They are found much more commonly in Pikmin 2 than in Pikmin.
Giant Breadbug
The Giant Breadbug is a boss in Pikmin 2. Unlike other Breadbugs, this one is large and has a more cubical shape, looking like a whole loaf of bread; it is by far the largest species in the Breadbug family. It acts the same as normal Breadbugs, but is harder to damage by "rejection" from The Ship, although you must only bring it to the ship twice to kill it. It is considered by many players to be the easiest boss in the game (boss theme music is not even played, though an exclusive tune is played only in the specific cave sublevel). The more recognizable habitat is located on the last sublevel (6) of the Glutton's Kitchen and consists of only two other Breadbugs, electric nodes, and Anode Beetles.
Dwarf Red Bulborb
Dwarf Red Bulborbs are small, common enemies in the Pikmin games. They perfectly resemble Red Bulborbs in appearance, but with greatly diminished size. They also are diurnal, they are active during the day as opposed to most Grub-dogs. These enemies are easily defeated by swarming them, but throwing a Pikmin directly on top of one will lead to an immediate kill. Throw a Purple Pikmin on it and the Pikmin will remain attached to it while the creature falls. In Pikmin, these were known only to be a separate species from Red Bulborbs, but in Pikmin 2, they were revealed as members of the Breadbug family rather than Grub-dog family. Olimar's Notes in the Piklopedia confuse matters by saying he originally identified them as juvenile Spotty Bulborbs, which contradicts what the enemy reel at the end of the first game says; he must, therefore, have realised sometime before leaving the planet for the first time that the species were unrelated. In the first game, agitating one will make it unleash a cry, awakening the nearest Red Bulborb. This, however, doesn't happen in Pikmin 2.
Dwarf Orange Bulborb
The Dwarf Orange Bulborb is an enemy in Pikmin 2 alone. It mimics the Orange Bulborb, but, like all other Breadbug family members, it is diurnal, unlike the nocturnal Orange Bulborb. This simply means (as they are already awake) that they notice Pikmin at a greater distance than the Orange Bulborbs do. It can be very easily defeated by the swarming or aiming a single Pikmin throw to land on its back. These beasts are mimics of the Orange Bulborb like the Dwarf Red Bulborb is of the Red Bulborb, which makes them in no way, shape or form related to the Grub-dog family.
Snow Bulborb
Again, the Snow Bulborb is an enemy in Pikmin 2. They are another species of Dwarf Bulborb, these particular ones resembling miniature Hairy Bulborbs without any plumage. They are as similar to the beast they endeavor to copy as any other Dwarf Bulborb, and defeated in much the same way. Their most common location is in the vicinity of one or more Hairy Bulborbs, or in cave terrain of snow or ice.
