Sentret and Furret

Sentret
The Scout Pokémon
Type: Normal
Official Registration #: 161
Entry: A meerkat-like pokémon native to the grasslands of Johto. This small pokémon is famous for its highly cautious nature. It lives in groups and typically keeps itself low to the ground, within the brown, dry grasses of Johtonian fields. However, whenever it senses danger, it raises itself up on its thick tail to stand high above the grass and scans the immediate area for the source of its unease. The inches its tail adds to its height makes it easy for sentret to scan wide swaths of land … and for predators such as pidgeot, fearow, and trainers with impeccable aim to catch it right out of the grasses.

Furret
The Long Body Pokémon
Type: Normal
Official Registration #: 162
Entry: The evolved form of sentret, by battle experience. Because its body is slender as it is long, wild furret are capable of burrowing maze-like nests miles long. These nests are frequently so narrow that even rattata have difficulty squeezing through. In captivity, meanwhile, this behavior rarely changes, and trainers may need to be aware of keeping their valuables (such as, for example, your passport the night before you’re to leave for a conference in Unova) well-hidden to avoid having them buried deep in their backyards, in corners of nests that may only be excavated via Dig or a disgruntled furret.
