Pallet Town

Pallet Town is the first area of Red and Blue that is often regarded as a location to find PokéGods.

Origin
Like many locations in Red and Blue, tall grass can be seen outside of Pallet Town. Tall grass normally contains Pokémon, so it has been speculated that the tall grass outside of Pallet Town contains PokéGods. Pallet Town is more significant than other places since it is the first area to have tall grass outside of it.
