Belly Bag is a main character in the series Uncle Grandpa. He is a magical fanny pack which has infinite space and contains all of Uncle Grandpa's supplies. He is also Uncle Grandpa's best friend. He has appeared in every episode, since Uncle Grandpa takes Belly bag with him pretty much everywhere he goes. He is voiced by Eric Bauza.

Physical Appearance

Belly Bag is a red fanny pack with buttons as his eyes and zipper as his mouth. He has two straps on his sides that serve as his arms and/or legs and he has two silver buckles on the ends of his straps.


Belly Bag's personality is a complex mixture of willingness to help and support his friends, a voice of reason, sarcasm, and jokes. As seen throughout episodes, he is always there to help Uncle Grandpa out with his endeavors. However, Belly Bag sometimes realizes that Uncle Grandpa doesn't always do the right thing, so he tries his best to steer him in the right direction even if it doesn't always work. Belly Bag is also EXTREMELY sarcastic. His sarcasm is especially shown in Funny Face (toward Mr. Gus about why he wasn't invited to the Funny Face party), Uncle Grandpa Ate My Homework (toward Dennis in response to Dennis's sarcasm toward Uncle Grandpa), Shorts (toward Uncle Grandpa in regards to him destroying an orphanage), Leg Wrestler (making a sarcastic joke about Uncle Grandpa and Mr. Gus being all tied up in the match), and Board Game Night (in response to his lousy dice roll). Despite his constant sarcasm, he's also constantly explaining himself (shown in Uncle Grandpa Ate My Homework and Board Game Night) and constantly backing down if ignored or told to be quiet (shown in Nickname, Driver's Test, and Shorts). He also seems to flirt quite a bit, though his flirting is a bit awkward and sometimes creepy (good example of this would be in Tiger Trails where he asks "What's stoppin' ya?" in a flirtatious manner in response to when Uncle Grandpa says "I could just kiss you!". Another good example is in Jorts when he oggles Mr. Gus's jorts with Giant Realistic Flying Tiger).


Uncle Grandpa

Belly Bag and Uncle Grandpa are best friends and the two of them have never been seen without each other. Uncle Grandpa is the one who is seen interacting the most with Belly Bag and spending the most time with him. Whenever Uncle Grandpa needs something, he just reaches into Belly Bag and gets it out of him.

Mr. Gus

Mr. Gus and Belly Bag don't interact with each other much in the show, but in the episode "Uncle Grandpa Sitter", Belly Bag was seen leaving Uncle Grandpa to go have ice cream with him, implying that they are good friends.

Pizza Steve

Pizza Steve and Belly Bag are friends. They do not interact with each other that much, but they were making funny faces in the episode "Funny Face" and they were having ice cream together in the episode "Uncle Grandpa Sitter" without Uncle Grandpa. Belly Bag, however, has a tendency to spit sarcasm out at him (as seen in the Board Game Night short when he said "Sorry Buddy" when Pizza Steve got hit with 3 kids, a wife, and a mortgage)Belly Bag also warned Pizza Steve one time.

Giant Realistic Flying Tiger

Giant Realistic Flying Tiger and Belly Bag don't really interact much together but Belly Bag and Giant Realistic Flying Tiger were eating ice cream together in the episode "Uncle Grandpa Sitter" and they were seen making funny faces together in the episode "Funny Face".

Tiny Miracle

Tiny Miracle helped Belly Bag when his mouth was full of food he prepared for the gang in Big Trouble for Tiny Miracle along with other backbreaking tasks the gang made him do, also Belly Bag helped Tiny Miracle get the sauce RAM chops in Tiny's mouth so he won't explode.


Frankenstein lives in his castle that's inside Belly Bag as shown in Sick Bag, what happens to Belly Bag also happens to Frankenstein such as getting sick. In Body Trouble Belly Bag got mad at Uncle Grandpa while he was using Frankenstein's body.

Charlie Burgers

Belly Bag was very fond of Charlie when they first met in Charlie Burgers, Belly Bag really liked it when Charlie was sniffing him. Belly Bag and the others decided to help Charlie in his time of need and later on in Charlie Burgers he sacrificed his ball to save everyone from going into the black hole.


Since Samantha is Uncle Grandpa's laser hammer, it's stored inside of Belly Bag for safe keeping.
