There are actually four "first Pokemon" contenders: Bulbasaur is the first Pokemon in the national Pokedex. Arceus was the first thing to exist (but only took physical form later on.) Mew was the first Pokemon to be defined as a "Pocket Monster." Finally Rhydon was the first Pokemon designed in this world.
Drowzee is thought to be based on a tapir but may actually be based on the Baku, a spirit in Japanese mythology that, granted looks like a giant tapir but according to mythology is actually capable of eating dreams like Drowzee does, which is some thing most tapirs can't do.
