Tympole

Tympole is a round, tadpole-like Pokémon with a tan, circular face. It has large, oval, black eyes, a wide mouth with down-turned corners, and black eyebrows in the shape of quarter notes. Its spherical body is black with no visible limbs. Instead, it has two black-and-blue ringed half-spheres on either side of its head. These spheres are vibrated to create a sound too high-pitched for humans to hear. The sounds are used in rhythm to communicate with others of its kind, particularly for warning of danger. It has a long, blue tail with a fan-like shape and a black spot at its base. The anime demonstrates that Tympole swims and attacks in groups.
