LazyTown has partnered with US online company Brands on Sale to create a range of costumes.
The firm - which sells a variety of character costumes, including superheroes, adult, baby and toddler, plus stars such as Lady Gaga - has a line of outfits ready to roll out in time for Halloween.
It will be hoping to have the same success that the Sportacus and Stephanie costumes have achieved across Europe, selling well over 100,000 units.
"Costume sales are a mainstay for LazyTown, delivering awareness of the show and its characters in a way that few other licences can," said Magnus Scheving, CEO of LazyTown.
Johnathon Weeks, creative director at Brands on Sale, added: "We are a very large player in the US for toddler and children's costumes, so the inclusion of this licence is a natural to further strengthen our dominant market position."
