Bag is the title character in the puppet/animation series Big Bag. A sentient cloth tote bag with a mouth, Bag is of indeterminate gender, and is the best friend of Chelli. Bag helps Chelli to play and explore the world, often holding cardboard telescopes and other items inside itself. Though vocal, Bag usually communicates through a series of squeaks and mutterings, at times reminiscent of Beaker, though Bag is capable of some English, mostly with a notable speech impediment (such as saying "What's exploring?" as "Blut's blebloring?", etc.) This was the focus of one episode, "Attention Shoppers," when Bag is upset that no one can understand its voice clearly over the store intercom.
