look up any word, like eiffel tower:
A Pokemon from the second set(152-251) and the evolved form of Sentret. It sucks more than most of the first 151, but less than those from 252 onwards.

It is a normal type, based off of a ferret, upon which its name is a pun.
Look! Sentret is evolving
*evolving music*
Sentret evolved into Furret!
