To determine whether Big Foot is actually Snorlax, it is necessary to first define what we understand by the term "Big Foot".

Reports from sightings of Big Foot have indicated that is is "a large hairy ape-like creature, ranging between 6–10 feet (2–3 m) tall, weighing in excess of 500 pounds (230 kg), and covered in dark brown or dark reddish hair".

According to Bulbapedia, Snorlax has a height of 2.1 m and 460 kg. This puts it in the same height range as a Big Foot but double the weight. However, I believe this discrepancy may be explained by the uncontrolled eating habits of Snorlax, which can be seen from its unruly eating in the Pokemon TV show. In one episode where Ash won a cycling competition, Snorlax ate up ALL of the food given as a prize! Such a trend implies that Snorlax is actually Big Foot, whose long estrangement from humanity has caused it to become clinically depressed and induced it to turn to food as a relief. It is hence very likely that Snorlax and Big Foot are the same creatures.

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 sticking out. Its 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 foreclaws 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.

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 isn't 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.

I believe that it simply has big feet and therefore leaves behind big footprints, is rarely seen due to its habit of hibernating and most humans who have seen it have been stomached by it, hence the lack of witnesses. furthermore, with its thick fat, there is no surprise it is seen in snowstorms and the like. Finally, it can learn Ice attacks from generation I-IV, therefore being able to whip up snowstorms around its habitat, and maybe even a preference for such places.

I SWEAR IT IS LOLOLOLOLOL. IT WAKES UP WHEN YOU BLOW A FLUTE.

I THINK SO TOO!!! WHEE yes! big footie is actually snorlex!

Whatever. This is absoutely rubbish. I've had trouble catching Snorlax all along. It always burst out of my pokeball. WASTE MY INVENTORY. Poke balls are very expensive you know, 200 poke dollars each. Whats so good about snorlax anyway? All it does is to eat and sleep. Only know how to anyhow body slam people

its gotta be snorlax. this post is so random that this assumption would have to be true. it wouldnt just come outa my ass

Yes it is! Both are fictional characters. One cannot even justify the very existence of Big Foot. Snorlax.. well it's just a Pokemon character that clearly doesn't exists.
