Quite a while ago (last fall?) I supported a project on Kickstarter called "Obos."  The project was aiming to create a set of paper-based characters with interchangeable arms, legs, eyes, & tongues.  I really liked the designs (somewhat reminiscent of Yo Gabba Gabba, in a good way!) and also the fact that everything was paper-based.  I also loved that all the parts are interchangeable, so you can create your own monsters from the planet Obo.

Happily, the Kickstarter campaign surpassed its goal and we finally got our set a couple of days ago. I busted them out and my kids made short work of creating a bunch of monsters to play with.  Check them out!  You can get a set, or just a single Obo, from PlanetObo.com
