Wilbur's house, where most of the Pidgey live
Pudgy Pidgey Isle (Japanese: デカポッポ島 Deka Poppo Isle) is an anime-exclusive location in Johto. It is a small island located off the coast of Blue Point Isle in the Whirl Islands where extremely large Pidgey live. It appeared in Fly Me to the Moon.
The "Pudgy Pidgey", over time, lost the need to fly because there were no natural predators, thus did not have the need to escape. According to Professor Oak, the Pidgey ate but did not exercise. As a result of this, they ate so much they eventually grew overweight.
Pudgy Pidgey Isle is a mostly forested island. The island is connected to land only by a small rope bridge that sways in harsh wind. It has few paths and has a population of one. The sole human that made his abode there is named Wilbur. Wilbur feeds all of the Pidgey that live there and with a little help from his own Pidgey, Orville, is trying to persuade the resident Pidgey to fly. He has a small log house in a little clearing where the Pidgey live.
- Pudgy Pidgey Isle may be a reference to many islands where flying birds were able to reach and subsequently became large and flightless due to a lack of land-bound predators and an abundance of food. Examples include the Kakapo of New Zealand and the Dodo of Mauritius
- Wilbur and Orville are the names of the Wright Brothers, whom first accomplished powered flight.
