Company signs deal with Lucas Film, to manufacture and distribute the range in the US.
The deal includes a wide range of Star Wars talking plush toys and key rings based on the popular film.
The deal extends Underground Toys' relationship with Lucas Film, as it already holds the rights to distribute the line in the UK.
Hot Topic and Toys R Us have already signed up to sell the range. Hot Topic will feature the plush within its Empire Strikes Back anniversary celebration, while Toys R Us will launch the line in the summer.
