Pokemon Sun & Moon Evolution Guide: Grubbin (When & What)

Grubbin is a new Pokemon introduced in Sun and Moon that looks precisely like a tiny, disgusting insect. You should know, I’m biased against bugs. Look, that’s all I’ll say about it. It’s a Bug type, numbered 27 on the Pokedex, is usually found on Melemele Island (first one) or Akala Island (second one), and it evolves into some pretty cool bugs. But, you know, they’re still insects.

Here’s the official description for Grubbin:

Grubbin relies on its sturdy jaw as a weapon in battle and as a tool for burrowing through the earth. Grubbin loves electricity, which is why it can be found near power plants and substations. By wrapping tree branches in the sticky threads that it spews from its mouth, Grubbin can swing around like an actor on suspension wires!

Okay, okay, so here are the facts about this little critter. Grubbin will evolve at level 20 into Charjabug. This is both a Bug and Electric type Pokemon, it looks exactly like a green cube, and it has the ability “Battery.”

Charjabug

Here’s some official text about Charjabug, the second evolution for the trio:

Charjabug stays perfectly still in preparation for Evolution, and often spends time with its body half-buried in the earth. Charjabug is able to store up electricity. It can store enough power to run a household for a whole day. The power it stores can be provided to other Pokémon, so it can also serve as a battery!

Charjabug has the Battery Ability, an Ability not seen before in any other Pokémon. The Battery Ability allows it to raise the power of allies’ special moves.

Further than that, Charjabug will evolve into Vikavolt at level 40, which is another Bug and Electric mash-up type with the ability “Levitate.”

Vikavolt

Here’s what the official Pokemon site has to say about Vikavolt, the final evolution of the trio:

Vikavolt is like a fortress that zooms through the forest, firing a beam of electricity from its mouth. Its huge jaws control the electricity it blasts out.

Vikavolt is adept at acrobatic flight maneuvers like tailspins and sharp turns. It can fly at high speeds even as it weaves its way through the complicated tangle of branches in the forest.

Vikavolt clasps Charjabug with its legs and uses it as an extra battery. Even if a battle drags on, it can use the electric power from Charjabug to continue firing off powerful moves. When Vikavolt is engaged in a fierce aerial fight, it releases Charjabug to make itself lighter and increase its mobility.

That’s really all there is to the evolutions that Grubbin can undergo! For more help with Pokemon Sun and Moon, be sure to check back to Twinfinite’s wiki for guides and tips!
