Percy is the name of a Victorian doll that Pops had owned ever since he was a child. He had the ability to talk and spoke with a deep voice, which is strange since his appearance is that of a cherubic, really young British boy. He was the most sophisticated doll of his day, with 250 phrases stored inside, yet the only real phrases we heard him say had to do with an obsessive desire to draw on peoples' faces. Percy not only spoke of his obsession, but it was discovered that he was also an autonomous, "living doll" who actually carried out his intentions and threats of drawing on peoples' faces. He drew on Pops' face after Pops tried to throw him away, and when Pops tried playing teatime with him after Mordecai and Rigby threw him away, Percy became aggressive and wanted to draw on Pops' face more. Mordecai and Rigby tried to rescue Pops, but Percy escaped and went into the basement.
When Mordecai, Rigby, and Pops went after him, Percy knocked Mordecai and Rigby unconscious with a shovel. Percy demanded Pops to bring him a marker so he could draw on Mordecai and Rigby's faces but then Pops stood up for himself and told Percy that it's not cool for a grown man like him to play with dolls and that Percy must go away. Percy then ran towards Pops to attack him while Pops did the same. Pops kicked him into the furnace where he started to melt. He then climbed back out of the furnace while melting and collapsed on the floor.
He has old-fasioned black clothes with a white collar. He also has light blond hair and red cheeks.
- He is a parody of the urban legend "Robert the Doll".
- Percy is the second character to draw on Pops' face. The first is Rigby in "Dizzy".
- Percy is the second antagonist smaller than Rigby. The first were the Hot Dogs in "Meat Your Maker".
- In the basement, Percy told Pops to bring the marker, but he was shown holding the marker when he was hiding. He may have dropped it.
- When Percy ran to the basement his sprinting style is similar to Flapjack. This is possibly because J.G Quintel worked on The Marvelous Misadventures of Flapjack and Regular Show.
- He is like Slappy from the Goosebumps series and also like Chucky from the movie "Child's Play".
- He was not revived by Garrett Bobby Ferguson Jr. in Exit 9B, probably because he was just part of Pops' story.
