— David Winkle, Catchphrase
Mr. David Winkle is a pedophile, sex offender, and a serial killer/ rapist who appeared as the main antagonist in the Bowser Junior's 1st Grade! series. He first appeared in Part 2 of the First Grade series, where he replaced Mr. Wilfred as the teacher after Joseph accidentally broke Mr. Wilfred's hip while he tried to take Joseph's phone.
In his debut appearance, Mr. Winkle revealed that he is a sex offender and demonstrated perverted characteristics as well. He was arrested by Officer Goodman in Part 3 of Bowser Junior's First Grade after taking "school photos" of the students on his iPhone. The puppet for Mr. Winkle is from silly puppets George.
Mr. Winkle first appeared in Bowser Junior's 1st Grade! Part 2, as Bowser Junior's first grade teacher. He reveals to the class that he is a sex offender, and demonstrates abnormal, inappropriate, creepy and perverted behaviors. He also appeared in Bowser Junior's 1st Grade! Part 3, where he was arrested while taking photos of the students. He was replaced by Jackie Chu as Bowser Junior's 1st Grade Teacher in subsequent episodes of the series.
In Bowser Junior's 1st Grade! Part 5, Winkle returns to the school disguised as Jackie Chu. He fools everyone (except Cody and Jackie Twu). It is unknown how most people were oblivious to this even though he wrote "Mr. W" on the board, kept saying things "were hot", exhibiting his usual peverted behaviour and saying he was Jackie Chan instead of Jackie Chu. When the school burnt down from Junior lighting the paper on fire, he was arrested yet again, this time by Brooklyn T. Guy.
While he did not appear in this video, Mr. Winkle was mentioned as the murderer in The Gun! where he murders 15 kids at a playground, going from being a child predator to a child murderer with no explanation. He was arrested again after the police found his gun under the slide.
