As an AI language model, I do not have access to any specific information about a person named Ken Carson Goomba. However, "Ken Carson" is the name of a character from the popular toy line and media franchise "Barbie" created by Mattel. "Goomba" is a type of enemy character from the popular video game series "Super Mario Bros." It is possible that "Ken Carson Goomba" is a fan-fiction or a meme combining these two characters, but there is no official or widely recognized use of this name.
