I've wondered long and hard about what exactly os that fluffy white thing on Sesshomaru's shoulder, and now I have an explanation.Warning! This story is probably not true, unless by some weird twist of fate it is...
This takes place when Sesshomaru was a kid, maybe around when he was 200 years old. No Jaken or Inu-Yasha.
Disclaimer: I don't own Sesshomaru or Inu-Yasha, although it would be pretty cool if I did...
It was a particularily sunny day, the kind Sesshomaru hated the most. Everything was so cheerful and happy, it made him sick. The birds were extra cheerful, so he killed every bird that had the misfortune of passing by him.
He soon got bored of just sitting around killing birds, no matter how bloody the decapitated bird bodies were. So he set off, intending to kill whatever pitiful creature got in his way.
After about 15 dead demons, Sesshomaru stumbled apon a giant grey blob of goo lodged neatly in between two dead trees. Being bored, he decided to poke it with a stick as hard as he could.
Sure that wasn't the brightest idea he had, but at least it was something to do. Killing things gets kind of boring after awhile, and it's not too often you come upon a blob just asking to be poked.
He soon found a stick to his liking and proceeded to poke the blob.
Poke-silence-Poke-silence-Poke-silence-Poke
Sesshomaru found that poking this peculiar object provided him with great amusement and continued poking it untill...
Rustle!
Some movement! Poking this thing was getting better and better.
Poke-rustle-Poke-rustle-Poke
He was at the height of his amusement when...
A giant fuzzy white-ish thing leaped at him, emerging from the blob!
Being Sesshomaru, he dodged it, but was surprised when it swerved in mid-air and latched onto his shoulder.
He tried pulling it off, but it was stuck tightly, having bitten down onto his shoulder, using hook shaped teeth.
Sesshomaru then proceeded to kill it, using the stick he had found to poke it.
It was soon dead, but he found that he still couldn't pull it off his shoulder. Becoming increasingly annoyed at this creature he used all of his strength to pull, but it wouldn't budge. He then did something amazing.
HE SPOKE.
"!#$$#&&$#$&#!" Listing a bunch of swear words in demon language, which cannot be translated into English I'm afraid.
He soon got used to the !#$ on his shoulder (as he would say) and soon found out that the smell of the decaying carcass could be used as an advantage in battle. The smell would drive most demons unconcious, or really weak demons would die.
And that is the story of Sesshomaru's Fluffy.
