Okay, I just read the description of the videos from NicoNicoDouga. Apparently, an impassionate American Sonic X IMAS fan (heretofore referred to as "Sonic-kun") had been pestering the creator of those well-made MADs on Twitter... and the Japanese MAD-maker was so impressed with you-know-who's passion that he decided to give it a shot. The result is that Reach for the Skies MAD.
So, the creator told Sonic-kun about the video he made... and the following exchange happened:
( ^ω^) < ソニックソニックー作ったよー sm13854398
ヾ( ゚д゚)ノ゙< OKじゃあ次は"His World"で作ってよ
( ^ω^) < えっ?
ヾ( ゚д゚)ノ゙< ソニック20周年のロゴ入れてね
( ^ω^) < ………
ヾ( ゚д゚)ノ゙< 20周年おめ見たいな感じのセリフいれてね
( ^ω^) < ………
ヾ( ゚д゚)ノ゙< あ、あとパンチラショット見たい! パンツ!パンツ!
(#^ω^)< ビキビキ
(´・ω・`)< 正直すまんかった
( ^ω^) < ………
( ^ω^) < キュンときた
大体こんな感じ

( ^ω^) < Hey I made a "Sonic Sonic" video ー sm13854398
ヾ( ゚д゚)ノ゙< OK, then how about making one for "His World" next?
( ^ω^) < Eeh?
ヾ( ゚д゚)ノ゙< And include the Sonic 20th Anniversary too, yeah?
( ^ω^) < ………
ヾ( ゚д゚)ノ゙< With a line that says something like "Congratulations on your 20th anniversary", ya?
( ^ω^) < ………
ヾ( ゚д゚)ノ゙< Ah, and panties! I would like to see some panties in the vid! Panties! Panties!
(#^ω^)< ビキビキ (don't know what this means; think it's onomatopoeia for (#^_^))
(´・ω・`)< Sorry for being so forthright.
( ^ω^) < ………
( ^ω^) < *hugs*
It (our exchange) went something like that.
... And that's the story of how the second Sonic X Imas MAD was made.
