Wild Snorlax can be found sleeping in inconvenient locations throughout Kanto. In order to catch one, a Trainer must first awaken it with music from either a Poké Flute or Pokégear set to the Poké Flute channel.
Snorlax's body is composed of mostly its belly, where most of its fat reserves accumulate. It wakes up only to eat and seldom exercises. Its head is also large, and it has two pointed teeth protruding from its mouth. It has two eyes that are rarely seen open, giving it the appearance that it is sleeping. Its two hind feet, with three claws and a circular brown paw pad, are extremely large compared to most Pokémon, assisting its balance when it chooses to stand. Its arms and fore claws are short, but are long enough for Snorlax to grab its food and eat it, and strong enough to deliver powerful blows. It is usually dark blue or green in color.
When trained and exercised properly, Snorlax can gain supreme strength and ability. They can throw incredibly powerful punches and cause immense earthquakes. Snorlax have a strong digestion system, allowing them to eat anything (even moldy food) without getting an upset stomach.
Snorlax spend the majority of their time sleeping, surviving on their stored fat. Many Snorlax only awaken once a month, spending their waking time finding more food. A hungry Snorlax is not satisfied until it consumes 900 pounds of food, and then it goes back to sleep. If one ever sees a sleeping Snorlax, he or she should not wake it up, because these Pokémon become very grumpy if their peaceful dreams become interrupted. Several Psychic-type Pokémon using Dream Eater find this out the hard way. Aside from this, they are very docile and even allow children to bounce on their big bellies.
Snorlax are often in mountains and forests. However, they sometimes wander into towns and streets and sleep there. They have been documented in Kanto.
Snorlax are not picky, and will eat anything and everything that is edible---even other Pokémon. They are fond of large, thorny vines or their diet may compose of bananas found in grasslands. Snorlax only wake up to eat. They need to eat about 900lbs (90% of their bodyweight) to be satisfied before falling back to sleep. Some Snorlax sleep for a month at a time, so 900lbs of food is enough to sustain them for at least one month whilst asleep.
