Another toy has been found sporting this new Buzzworthy branding... the mega 1-step Bumblebee from the 4th Movie in 2014, for US$30.
That makes it six toys now in this new set of packaging.
It was found at a Target store in the US, which could mean that the line is a Target exclusive line. (I can't imagine this being a general release line, as Bumblebee isn't THAT popular to the older collectors that most of his line is aimed at, so a retailer (Target) MUST have actually asked for a set of mostly Bumblebee toys in Bumblebee themed packaging... as there is no movie coming out soon.)
