Fans of the Pokemon franchise know Snorlax is a rather lazy and gluttonous Pokemon. Snorlax is one of the original 151, and is currently not able to evolve. However, it received a pre-evolution, Munchlax, in Generation 4. Those looking to use Snorlax to defend gyms or in PVP in Pokemon GO should make sure it has good IVs and a good set of moves.
