Betony Burrito Jakson IV, with the full title Beth the Pup Princess, is a character from the future in the Adventure Time series. She is a good friend of Shermy, who made her first and only appearance in the series finale Come Along With Me. As you understand, this character is a large, round, yellow pup. As Jake's descendant, she shares his eyes, ears, jowls, and similar fur color. Beth also has small ears and a large belly button, and she doesn't seem to have a nose. You can see all of that in our fanart Adventure Time Beth and Sword cursor pack.
