Belly Bag

Uncle Grandpa's talking red fanny pack and his closest friend, who carries all of his priceless valuables especially Uncle Grandpa's weapon of choice, his laser hammer. Belly Bag's insides contain many weird objects and dimensions, including a castle where Frankenstein's Monster lives. Despite being practically attached to Uncle Grandpa, Belly Bag has the ability to walk and can produce multiple hands from inside his body. He even has the ability to see despite having no visible eyes. In the second Uncle Grandpa short, "Secret Mountain Uncle Grandpa", he is referred to as "Fanny Pack" and is voiced by Paul Rugg. His catchphrase is "What's cookin', good-lookin'?"
