The mixable collection lets fans customise their own Monster Mixter by choosing leg and arm designs.
Build-A-Bear Workshop has released its first propriety property, in the form of Monster Mixters.
The mixable collection features two body options, four leg designs and four arm styles, which are sold together as a set.
Additional parts, including feet and wings, hands, a monster sound chip and costumes are also available for fans to purchase separately.
Online shoppers will also be able to take part in the customisation of Monster Mixters, with the Build Your Mixter experience.
Monster Mixters are available now at Build-A-Bear Workshop stores, as well as online.
