Ruffians

Ruffians are the four minions of Professor Pester in the Viva Pinata franchise.

In the game series, they rampage garden, coughing up toxic candies, opening gates and destroying fences, starting fights with piñatas, and damaging ponds by filling them in. They will not leave unless they are bribed with Chocolate Coins, or a Barkbark with a Spiked Collar or a Captain's Cutlass scares them away. A Mallowolf can also scare them away with its howl. A Smelba can scare them as well.

In the TV series, he reveals that he started out with five Ruffians, and one of the Ruffians fell into the pot he was using to create his Sour piñatas and the Ruffian died, which left only a mask in the pot. However, the Sours were a failed experiment for him because he couldn't control them.
