Drilbur
The Mole Pokémon
Type: Ground
Official Registration #: 529
Entry: A foot-tall mole-like pokémon native to the cave systems of Unova. An extremely skilled digger, drilbur can dig through even solid rock at speeds of up to thirty miles an hour. It can therefore give cars running aboveground a good race. This is a fact that has actually been published in the Unovan pokédex, which honestly says more about either Unovan cars or past-times than it does about drilbur.
Excadrill
The Subterrene Pokémon
Type: Ground/Steel
Official Registration #: 530
Entry: The evolved form of drilbur, by battle experience. Upon evolution, excadrill gains steel-tipped claws and a drill-tipped helmet, both of which enable it to burrow up to 300 feet into the ground and/or straight through iron plates. It creates elaborate tunnel systems for labours consisting of scores of drilbur and excadrill, but such systems have been known to inflict damage on human structures, specifically subway systems. Luckily—considering the fact that excadrill’s native Unova has only one tunnel system that loops beneath Nimbasa and Anville, neither of which are places where excadrill are known to live—the actual damage to human construction the average excadrill causes tends to be minimal at best.
