Frogadier

Frogadier is a light-blue, bipedal, frog-like Pokémon. A dark blue marking covers its head and forms a three-pointed mark down its upper back. Its eyes have yellow sclerae, black irises, and white pupils. Its eyes protrude slightly from the top of its head and each has a backward-facing spike above it. It has a white bubble scarf, dark blue hands and circular toes, and white circular fingers.

Frogadier is a nimble and swift Pokémon; it can scale a tower exceeding 2,000 feet (600 meters) in one minute. It can also throw bubble-coated pebbles at targets up to 100 feet (30 meters) away. It can confound opponents by leaping about ceilings or into trees
