Pokédex entries

What each game says about it, in the games' own words.

YellowBurrows at high speed in search of food. The tunnels it leaves are used as homes by DIGLETTs.

SilverIt rapidly bores through the ground at 50 mph by squirming and twisting its mas­ sive, rugged body.
CrystalAs it digs through the ground, it absorbs many hard objects. This is what makes its body so solid.
Ruby / SapphireONIX has a magnet in its brain. It acts as a compass so that this POKéMON does not lose direction while it is tunneling. As it grows older, its body becomes increasingly rounder and smoother.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
