Role in the series
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.
- Bubba is similar to Cave Pup from 101 Dalmatians: The Series, as both are prehistoric characters who find themselves in a modern setting, and both have similar sounding voices.
- When a Donald Duck meet and greet was added to the Cretaceous Trail at DinoLand U.S.A. at Animal Kingdom, a drawing of Bubba was included on a bulletin board's timeline of prehistory.
