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 stretches out past its shoulders. It has four flippers which are the large ones with white markings isolating its toes and the small rear ones.
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.
Popplio when standing on its fins bears some resemblance to the alchemical symbol of mercury (representing Water).
Popplio gained notoriety when an alleged leak of its final evolution depicted a creepy-looking circus clown seal which earned Popplio much negative opinion on the internet. Fortunately, the reveal of its beautiful mermaid-like evolution Primarina brought it back to fanbase popularity.
Popplio is based on a sea lion and the Hawaiian monk seal. It is also based on the classic depiction of a circus performing seal, with the collar around its neck and balancing a ball, or bubble, on its nose.
Popplio is a combination of pop (as in popping bubbles) and lio, the first three letters of lion in sea lion.
