Let me introduce you to the world of Carnimals. This is a new line of toys from Megahouse, and—like most great products created for pure entertainment—has a fun backstory. Carnimals are actually alien life forms from a planet called Sua. On Sua, Carnimals coexist happily and peacefully with spacemen. They’re actually living vehicles, not animals, and they’re fueled by the mysterious Anima spirit that lives in the Sua Forest. They have a lifespan of 100 light years.
