Professor Pester is a character who wants to destroy Piñatas to get their candy. His attempts usually fail, with various results.

He has four Ruffians, but he started out with five at first. One of the Ruffians fell into the pot he was using to create his Sour piñatas and the Ruffian died, leaving only a mask in the pot. However, the Sours were a failed experiment for him because he couldn't control them.


  • Victory is mine!
  • I have no regrets!
