I Never Knew That Rudolph Had A Son,

named Robbie,

at least he does according to the BBC. They developed three cartoons based on Rudolph's offspring, but the name of Robbie's famous dad is never actually mentioned. The plot line tells us that the villain of the series, Blitzen, can't stand to hear Rudolph's name, allegdly, it's because the BBC couldn't get permission to use it (or didn't want to pay to use it), if you haven't seen the British version but still remember Robbie, that's because Fox Family ran the show for a few years in the early 2000s with redubbed voices, including Ben Stiller as Robbie, Hugh Grant as Blitzen, Britney Spears as Donner, and Brad Garrett as Prancer, how did the song go? 'Robbie the un-rednosed reindeer!'.
