Argos acquired the Chad Valley brand last year following the demise of Woolies and has now drafted in Rocket Creative to work on refreshing the range.
The firm has conducted a research programme to identify where the brand should sit within the market, before starting to work on the new offering.
Rocket Creative has previous toy experience and has worked with brands such as Toymaster, Inspiration Works and Hy-Pro.
Andrew Turner, marketing manager at Argos said: “The Rocketeers have worked wonders so far developing some amazing concepts and successfully meeting strict deadlines with ease.
"I think it’s safe to say we are all getting very excited about unveiling the final designs.”
The new products will be launched later this year.
