Pokemon Gen 7 775 - Komala

This Pokémon stays asleep from birth to death, staying this way because of its diet of leaves containing sedative properties. While its expression sometimes changes as if it is aware of its surroundings, this appears to be a result of its dreams instead. It is able to eat, travel, and even battle without waking. If the log pillow it clings to is removed, it will be unable to sleep well and thrash wildly.
