Quick Help Please! ID this vintage rainbow brite thing?

[Thunderwing]

I have this rainbow brite 'sleeping bag'. Any ideas what it is? I'd like to sell it, but can't get a proper idea of price until I can figure out what it is and find it on ebay.

Think that came with the Rainbow Brite Slumber set. No idea on value.
