Doduo

Doduo is a bird that makes up for its poor flying with its incredible speed. As it runs, it leaves behind giant footprints. In "Showdown at the Po-ke Corral," Ash returns to Pallet Town to train for the Pokemon League. Ash and his rival Gary go on a tour of Professor Oak's Pokemon research and communication center, and as they walk about, they meet Gary's captured Doduo.
