It is not known to evolve into or from any other Pokémon.
This Pokémon spends most of its time sleeping, but when it's awake, every one else starts sleeping. This is because of a substance on its body making every one pass out. It's hard to make friends when they are always sleeping, but they tend to like Zeeleep and Zeerealm because they can visit their dreams.
While Dozand look and act as if they are awake, they are actually in permanent sleep. They are able to navigate in the real world while only seeing their dreams.
