Vernon Trumpski is an overweight child similar to Cartman in appearance and mannerisms, even trying to control his mother. Vernon somehow came into possession of Lemmiwinks after his escape from Mr. Slave's rectum. Vernon appears in "Bass to Mouth", when the boys and other students of South Park Elementary take Lemmiwinks from him to stop Wikileaks.
The children and staff of South Park Elementary rush over to Vernon's home to retrieve the rodent so he can fight his brother Wikileaks and stop the gossip on Eavesdropper. It was never revealed how he came into possession of Lemmiwinks.
Vernon is overweight. He has curly brown hair and freckles. He wears a white shirt tucked into gray pants. He also wears an unbuttoned, green shirt over his white shirt.
