The whole Furby thing is apparently a meme from a 2ch post.

ファービーがおねだりしてきた

ファービーが「ﾅﾃﾞﾅﾃﾞｼﾃｰ」ってうるさいから
頭の上にマッサージ器あてて死ぬほどナデナデしたら
「ﾌｧｰ…ﾌﾞﾙｽｺ…ﾌｧー… ﾌﾞﾙｽｺ…ﾌｧ-」ってなった。
最初は面白かったんだけど、なんかキモくなったので首元を横から思い切りチョップしたら
「ﾓﾙｽｧ」みたいなこと言いながらすごい勢いで飛んで行った。

Furby pestered me.
Furby wouldn't shut up, saying "pet me pet me!"
I put a massager on top of his head so he could be pet until he died.
He said "faa burusuco... faa burusuco... faa."
It was amusing at first, but it somehow started becoming creepy, so I did a hard chop to his neck.
He said something like "molfaa" while he flew away.

ﾓﾙｽｧ = molsaa, not molfaa. Fixed.

Furbugi.

"MORE, Snake! Pet me MORE!"

...Was the first thing that came to mind...
