Bonus Episode: A special eight-minute short was released on the Wii Channel in Japan. It was dubbed and available on Nintendo Video for Nintendo 3DS, three years after its original release.
Cash Cow Franchise: Nintendo of America attempted to turn the Kirby series as a whole into one when bringing the anime overseas - but while the games and show remain popular, the only merchandise it managed to produce in Western markets was a handful of [VHS] tapes and DVDs.
Admittedly, Nintendo wanted to make Kirby "the next Pikachu". More or less, this did not happen.
Executive Meddling: The "Air Ride in Style" two-parter. In the original, these episodes (called "Crisis of the Warpstar") came close to the end of the series, and were supposed to be Kirby's training for the final battle. In the dub, they were stuck in the middle of the series in order to advertise the then-new game Kirby Air Ride.
Also, Sheepwolf from the episode "Sheepwrecked" sounds like Giovanni.
And you can't stop the Customer Service guy because he's voiced by Dan Green!
Italian dub? King Dedede is Franky and Meta Knight is Batman.
Keep Circulating the Tapes: This series only really received a handful of VHS/DVD released from 2002-2008, all in all not counting multiple releases and counting the Fright to the Finish movie which is the final 5 episodes merged into a single film with a bonus episode as a special feature, and counting the 3 episodes included on the 20th anniversary Wii game, which also includes the first episode, which as mentioned before has been released at least twice, only 25 episodes out of 100 have ever gotten a DVD release in America, literally only 25% of the series has ever been released. This series is semi-reliant on continuity and a lot of key episodes haven't even been released! Especially in the movies case where we see several characters from episodes not even on DVD!
In the original, there's actually quite a few. For instance, Takashi Nagasako as Mayor Len and Professor Curio; Nobuo Tobita as Chief Kawasaki, Kabu, Galaxia and others (including Macho-San); and Yuko Mizutani as Mabel, Waddle Doo and several Demon Beasts. Kirby and Hohhe also have the same actress in the original.
