Pokédex Info:
Snorlax are rare, extremely lazy, and very big. They prefer to eat and sleep rather than battle. In the wild, it takes over 900 pounds of food to satisfy a Snorlax's hunger, but that's not a problem because they'll eat anything. (Snorlax use less energy in their Poké Balls, so they don't need to eat as much.) Snorlax will sleep anytime and anywhere, even if it happens to be in the middle of a battle.
