The challenge with Diglett is not finding one
     but capturing it before it faints or runs away —
     so make sure to keep a lower-level Pokémon
     with you as you head into Diglett's Cave.
     Another interesting trait: Diglett don't evolve,
     but they do band together in groups of three.
