Charles Franklin Marbles is Jenna Marbles' first dog. He is a male chihuahua and he was born on June 5th, 2008. He is described as being a very sweet and loving dog but also not having much intelligence. He was named after Mr. Marbles from the popular sit-com "Seinfield". Marbles is the alpha male and will hump Kermit on occasion to assert his dominance. Marbles also has a favorite stuffed bear who he humps every night before bed. Marbles adores Jenna and is very attached to her as she is to him. It took Marbles a long time to adjust to Julien and accept him as "a daddy". Marbles is a very docile and calm dog most of the time leading people to make incredibly intelligent and lovely jokes that he is dead, despite countless request from Jenna and Julien to continue these comments.
