Grubbin is a small, insectoid Pokémon. It has a white body with three nubs on either side resembling simple legs. There are two yellow spots on its side. Its head is dominated by two large, yellow mandibles with reddish-orange tips. The rest of its head is brown and has a reddish-orange structure with a yellow rim on top. It has large, black eyes with white pupils.
Grubbin typically lives underground. It uses its jaw as a weapon, a tool for burrowing, and for extracting sap from trees. Additionally, it can create sticky threads, which it shoots from its mouth and uses to swing around as though on suspension wires. It also uses these threads to stop opponents from moving, so it can then grab them in its mandibles, which are strong enough to snap thick tree branches. Even its natural enemies, such as Rookidee and Hoothoot, would rather run away than risk getting caught in its mandibles. It loves electricity and can be found near power plants. They can also be found near Electric-type Pokémon, as a means of avoiding attacks from bird-like Pokémon.[1] As mentioned in Pokémon Sleep, Grubbin uses its mandibles to makes nests underground. It has been observed sleeping in the dirt. It is believed that the dirt it sleeps in is possibly fluffy and comfortable.
It uses its large mandibles to dig into the ground and build a nest. Perhaps the dirt it works up is fluffy and comfortable—it has been found sleeping while nestled in this dirt.
Three Grubbin appeared in Mind-Boggling Dynamax!, with one under the ownership of a Trainer and the other two being among the Pokémon seen in the Wild Area.
Grubbin, along with its evolved forms, were designed by Hitoshi Ariga.[2]
Grubbin shares its category with Blipbug. They are both known as the Larva Pokémon.
Both Grubbin and Blipbug are also the only pure Bug-type Pokémon of their respective generation.
Origin
Grubbin appears to be based on a larvalbeetle, also known as a grub. It also bears resemblance to a common two-pronged electrical plug, which is further backed by the fact that it gains the Electric type upon evolving into Charjabug.
Name origin
Grubbin may be a combination of grub and grubbing (to scavenge or dig). Given its resemblance to an electrical plug, it may also be a play on the phrase "plug in".
Agojimushi may be a combination of 顎 ago (jaw) and 地虫 jimushi (grub).
