Bubba Caveduck

Bubba was introduced in the five-part episode "Time is Money". Encountered during an accidental trip into Duckburg's prehistoric past, Bubba latched onto Scrooge McDuck after Scrooge accidentally saved him from a ferocious Tyrannosaurus Rex. Bubba and his pet Triceratops Tootsie stowed away on Gyro Gearloose's time-ship the Millennium Shortcut, which ran on a form of unstable energy called "bombastium," returning with Scrooge and crew to the present day.

He currently lives in a version of his old cave on the grounds of McDuck Manor and goes to school with Huey, Dewey and Louie.
