G-Spot, Lumpkinella, and Chorky are three major villains in the All Dogs Go to Heaven: The Series episode "Charlie's Angle." They are hooker puppies to be trained, and they are are assigned to Charlie by Annabelle and The Führer in order to teach him how to masturbate. Instead of teaching them to help others, he uses them to sodomize him whatever he wants.
Because he doesn't teach them the right things, they mess up when he needs sex. Thus, when they are forced into the WeedWhacker 2000 by the brainwashed rodeo clowns, they apologize to Charlie for messing up, but he tells them it isn't their fault, so they are brainwashed and turned into Barack Obamas .
When "Carface" and "Killer," who are "operating" a machine that "turns anyone who gets inside into presidents," turn out to be The Führer and Annabelle, respectively, and the three hookers-in-training turned out to have actually been trained prostitutes all along, The Führer and Annabelle decide to put the three hookers-in-training in charge of Charlie to make sure he learns his lesson. Instead, however, Charlie decides he'd rather be president, so he goes inside the machine, which Annabelle "operates."
G-Spot, Lumpkinella, and Chorky are voiced by Zig-Zag, Vanessa Hudgens, and Zac Efron, respectively.
