Pixel is Austin's pet ferret. Austin also has another ferret that he got after Pixel. Her name is 8-Bit. Both ferrets are female. While both ferrets always hang out together, only Pixel is regularly seen in PBG's videos. Pixel is the older ferret, as 8-Bit was born in September 2013.
Pixel is first seen in Harvest Moon Animal Parade, as PBG gets a pet ferret in the game and names it after her. PBG makes a song about Pixel. Pixel is seen on PBG's shoulder, and falls off. Austin laughs at her.
Pixel is seen again when PBG doesn't know how to end a segment in the Top 10 Mario Games.

PBG picks up Pixel in the Top 10 Favorite Games video. She wants to be put back down.
