Cheesecake (voiced by Andy Daly) is Wolf's friend who comes to visit in s3e4 “Code Enough Said Adventure”
He returns in s3e10 “Xmas with the Skanks Adventure”
Cheesecake is warm and optimistic, but gets in trouble often because of his drinking. Despite not often being in the show, he is Wolf's best friend and they grew up together. He cares about Wolf and that is shown but we don't know much about their past or how deep their friendship runs. We just know that Wolf has mentioned that Cheesecake has always been there for him and it Is commonly assumed he was one of the only people there for Wolf after Kathleen left.
