“Popplio's swimming speed is known to exceed 25 mph. It's better at moving in the water than on land. Still, when it's on land, it takes advantage of the elasticity of its balloons to perform acrobatic stunts and jumps.
Popplio can snort out balloons made of water! Watch it spin water balloons into a playful battle strategy! Both frivolous and hard-working, Popplio can easily get carried away—unleashing enough power in battle to make quite a spectacle! But Popplio’s determined spirit means it can usually be found practicing hard on its balloon skills. The Water Gun move attacks an opponent by firing a jet of water. Popplio knows this move from the moment it becomes your partner!”
Popplio is a pinniped Pokémon that is primarily blue. It has large eyes, a long, white snout with black whiskers, and round, pink nose. There is a small, rounded earflap on each side of its head. Around its neck is a light blue ruff, which extends past its shoulders. It has four flippers. The front flippers are larger than the hind, and have white markings separating its toes. Popplio is able to snort bubbles of water from its nose, which it uses as part of its battle strategy.
