Hoothoot is an avian Pokémon that resembles an owl with a round body. Most of its feathers are brown, but its belly is cream-colored. It has large, red eyes; a small, pinkish beak; stubby wings; and a fan-like tail with three feathers. Encircling its eyes are black rings; the lower rims of the ring have three protrusions that resemble the teeth on a gear while the upper rims have extensions that resemble the hands of a clock. As seen in the anime, Hoothoot's feathers can grow to be shaggy, and the protrusions on its head droop. It has two pinkish feet, each with five-clawed toes. However, it will typically only stand on one foot at a time and alternates between the two at speeds too difficult to track with the naked eye.
Hoothoot begins crying at exactly the same time every day and always tilts its head in the same rhythm. This ability is due to a special organ that senses the world's rotation and allows it to keep track of time. As a result, Hoothoot was considered a divine messenger of time and raised to serve as clocks a long time ago. Some Trainers still use it as a clock today. Hoothoot is most commonly found nesting in trees in temperate and boreal forests. Hoothoot is nocturnal, and during the day, it sleeps in holes carved into tree trunks.
