Its not technically a chocolate bar butt....does anyone remember Romereo ice creams?? They were a choc ice the same shape as a Twister (but no stick) and I think they were by Walls. The ice cream inside was 3 different flavours twisted round (again like a twister) of malt, chocolate (or fudge?), and vanilla (or white chocolate?) and coated in chocolate. They were lovely but i only remember them being around for one or two summers in the mid-80s.
