#535
Tadpole Pokémon
Tympole is a Water-type Pokémon, No. 535 in the National Pokédex, introduced in Generation 5 (Unova region).
« It uses sound waves to communicate with others of its kind. People and other Pokémon species can’t hear its cries of warning. »
Tympole is a small, round, tadpole-like Pokémon with a tan face, large black eyes, and a downturned mouth. Its black body has no limbs, blue-and-black cheeks, and a long blue fan-shaped tail.
By vibrating its cheeks, it makes a sound too high for humans and uses rhythm to talk to its own kind and warn of danger. It evolves into Palpitoad, then Seismitoad.
While Ash looks for Remeyo weed, Tympole led by a wild Palpitoad attack his Oshawott underwater. They flee when Oshawott strikes them.
The design joins a toad tadpole and a loudspeaker; bumps suggest headphones, warts, or a tympanum. The name may blend tympanum with tadpole. Tympole and Palpitoad were designed backward from Seismitoad.
