Popplio is a blue sea lion Pokémon. It has large eyes, a long white snout with a pink round nose and black whiskers. It has two ears on each side of its head. Around its neck is a light blue ruff collar which extends out past its shoulders. It has four flippers which are the large ones with white markings isolating its toes and the small rear ones. It also loves to blow bubbles and bounce them around.
Popplio will frequently work on blowing bubbles and try to get them larger than their bodies. Instead of walking, Popplio will generate and use their bubbles as a springboard, popping as they leap on top of them in order to get a bounce out of them as they pop, in turn allowing them to perform acrobatic stunts in their leaps to please those they enjoy playing with.
It can blow out many balloons with its nose. It can swim at 25 mph (40 km/h).

Popplio, Seel & Dewgong are all known as the Sea Lion Pokémon.
Popplio is a combination of the classical depictions of a performing sea lion and a circus clown, with the collar around its neck, white face, and nose resembling a clown nose. It could also be a reference to the Hawaiian monk seal.
Popplio is a combination of pop (as in popping bubbles) and lio, the first three letters of lion in sea lion. It might also use "ilio-holo-i-ka-uaua" which is a species of Hawaiian monk seal. It might also come from pōpō, Hawaiian for ball (seeing how Popplio balances bubbles on its nose like a circus seal would do to a ball).
