Drowew is impish and selfish, only thinking in terms of its next meal of dreams. It will sneak up on others to put them to sleep, no matter what they may be doing and what the consequences will be, just to sate its hunger for their dreams.
A Drowew is said to possess the genes of all Pokémon. If your nose becomes itchy while you are sleeping, it's a sure sign that a Drowew is standing above your pillow and trying to eat your dream through your nostrils.
