Professor Tree's Pidgey are a pair of Pidgey that incessantly follow Professor Tree, often causing destruction and eating his food.
Appearance[]
Both Pidgey look like normal Pidgey. However, Professor Tree claims that they follow his scent, so they may have a better sense of smell than the average Pidgey.
History[]
The two Pidgey inhabit Beige Town, or the surrounding area. Professor Tree mentions that his job requires him to survey Pokémon. Of course, he does this haphazardly and only "counts Pidgeys once in a while."
They break into his lab after Professor Tree's Kakuna is taken. Professor Tree comments that two Pidgey are a "new record," as they flap around the lab, breaking his bong.
Later, Professor Tree set out for Celadon City to buy a drug-filled bike from the mall only to discover that the cashier sold it to a child. The Pidgey break into the mall, either through a window or door and chase the professor away, with him yelling that they followed his scent.
They were last seen having followed the professor to Nugget's Herb Shop. After the documentary is interrupted by the newscast of Viridian City under police siege, they break in to the shop and eat his Pringles.
