Dastardos is the evil version of Stardos who became evil after Pester fed him Sour Candy. He was originally a good person until Lester Pester became evil and terrorized the Island.
Sort of like Pester, Dastardos also tries to destroy your garden. But, he will go away after a while unlike Pester's continuous Damage. He is seen wearing a mask, and having a dog sour.
However, he didn't appear in the show nor mentioned by Pester.
But, he did appear in the intro of the show, and was seen waving at the camera.
- His name is a parody of the word, Dastardly.
