Inner Monster is a line of materials to create custom dolls with that was launched in 2014. It follows on Create-A-Monster, which was active from 2011 to 2013. Inner Monster utilizes many concepts introduced by Create-A-Monster, but improves on some of them, like using masks and integrated rotating eyes to customize a doll instead of relying on a finite amount of tattoos or temporary temperature. All of its starter pack dolls come with the full set of parts, which follows from the final developments of Create-A-Monster. Inner Monster also allows people to customize inside the doll's torso, which takes the Create-A-Monster experience another step further.
