Fluffy is the doodle Flippy found during the construction of the Event Grounds when preparing for ToonFest 2014. He usually makes an in-game appearance standing next to Flippy whenever ToonFest is present. Ever since then, there was something about ToonFest that made Fluffy wander off, which allowed him to eventually return to Flippy with other doodles. Because of this, Toons had been able to adopt a doodle at the Pet Shops.
- Fluffy appeared in Toontown Online in 2004 when Flippy lost him. Toons looked everywhere until Minnie Mouse found him in Minnie's Melodyland.
- During ToonFest 2014, Fluffy had randomized appearances due to a bug with his color.
- When Barbecue Headquarters opened as ToonFest on April 1, 2015, Fluffy mentions "Home is near!", which may hint that doodles were nearby.
- Right after ToonFest 2015 ended on October 20, 2015, Flippy found out that Fluffy had gone missing. Beforehand, Flippy mentioned how there is something about the ToonFest grounds that makes Fluffy wander off.
- Suspiciously, when Fluffy went missing in Toontown Online, he came back with many other doodles, deputing the release of pets to the game. This leads to a hint that the same thing will happen in Toontown Rewritten, as the game follows the original storyline.
- During Operation: Storm Sellbot Headquarters, Flippy offered Toons a special ToonTask to help find Fluffy's collar that was lost somewhere around Sellbot Headquarters.
- Fluffy appears on the back of Flippy's trading card, which was one of the newly-released Toontown Rewritten trading cards distributed at OMG!Con 2016.
- During April Toons Week in 2017, Fluffy roamed around Toontown by appearing in buildings throughout the streets to search for Flippy.
