The SSB wanders the forest, looking to stuff anyone she can into her soft insides and cuddle with them whether they want to or not, only releasing them after a night of warm snuggling. After receiving substantial affection she can shed her skin, essentially creating a sleeping bag anyone can take with them and use; furthermore, reading the tag inside the skin transforms the reader into a SSB as well (reading it again reverses the transformation.)

So I introduced  RedXIX to Serperior, and he wonders what the inside of the collar is like...and then I came up with this! Ah, I want one of these myself. Protection companionship and a warm bed, all in one.
