Doduo, known as the Twin Bird Pokémon, resembles an ostrich or a roadrunner, with sharp beaks and an extra head. It may also be based on the kiwi. Its name is a portmanteau of the words dodo, the extinct flightless bird, and duo, in reference to its two heads. Doduo's tracks are huge and very distinctive. It inhabits and races across grass-covered plains at 60 mph. It is well-adapted to dry and arid climates. Doduo's second head is said to have been formed by a sudden mutation thousands of years ago. Both heads normally contain identical brains, although rare cases have been observed where a Doduo has two distinctly different brains. Interestingly, Doduo can be caught in the wild in all of the Pokémon video games. Doduo can also be found in Pokémon Snap. In the Pokémon anime episode "Bad to the Bone," Jessie of Team Rocket battles a Doduo with her Arbok. The battle is interrupted when the Doduo's heads begin to fight with each other. In Pokémon Ranger: Shadows of Almia, the player can ride a Doduo to get around faster.
